Smart phones and tablets have revolutionized how we communicate, access and use information, work, travel, play and learn. Chemistry education and the field of chemistry have not surprisingly been positively impacted by this technology as useful educational material, databases and other tools have been developed in recent years for chemists and chemistry students. Among the many important fields of chemistry, organic chemistry with its powerful graphical language seems perfectly matched to take advantage of the educational opportunities smart phones and tablets have to offer. Their high-resolution LCD display and touchscreen technology together with applications (apps), which are the most commonly used and popular features of mobile devices, makes drawing, presenting and interacting with organic structures trivial.

Nature Chemistry readers interested in organic chemistry might find the following selection of free or moderately priced apps focused on drawing (ChemJuice and ChemDoodle), organic synthesis (Chemistry By Design), 3D molecular viewing (Molecules, Atomdroid and NKDmol), compound searching (ChemSpider) and periodic table (EMD PTE) to be of interest. Although some specific content types or features of chemistry texts or references lend themselves to being recreated in app format, it is far from clear that all would be suited for such a transition. An exciting and important exception is the new Strategic Applications of Named Reactions in Organic Synthesis (SANROS) app by Lazló Kürti and Barbara Czakó based on the popular book of the same name and published by Elsevier. The book version was already popular for its concise and masterful presentation of the most commonly used named reactions in organic chemistry, but immediate access to this valuable source at your fingertips is only one of many benefits that make the app version more appealing than the printed one.
In many ways the app platform has allowed the book to come alive with the addition of several useful interactive and search features. For example, a list of more than 450 abbreviations of most frequently used reagents, solvents and catalysts can be searched and accessed at any time with the full chemical name and structure being displayed. Another useful feature is the ability to search by reaction categories (oxidations, rearrangements, ring expansions and so on) to find representative named reactions. My personal favourite is a new feature called Specify Transformation, which allows the user to search the 250 named reactions by initial and/or target functional group (allene, diene, epoxide and so on). I found myself searching for 'allene' as a target functional group and was delighted in rediscovering Doering-La Flamme allene synthesis, a fantastic reaction.
My only reservation is that I wish it was priced more moderately to make it more attractive to undergraduate and graduate students as well as post-doctoral fellows in the field. I eagerly await the launch of the full iPad version and I certainly hope that an android version of SANROS will be launched soon so that the armies of Android and PC-device users will be able to enjoy this wonderful app. It is important to note that SANROS is not the only app product on the market that tackles named reactions: an elaborate app called NAMED REACTIONS PRO from Synthetiq Solutions is also available from the App Store ($9.99).
The design of synthetic routes to natural products and other medicinally relevant organic compounds will be covered in detail. Retrosynthetic analysis, substructure keying, and pattern recognition, along with other methods for synthetic planning will be discussed within the context of specific case studies. Classic and modern organic reactions, including asymmetric synthesis and catalysis, will be introduced and their application in synthetic planning examined. Case studies will include the synthesis of terpenes, alkaloids, polyketides, steroids, proteins and pharmaceuticals. The end result should be that students are familiar with the important issues associated with synthesis and gain intimate knowledge of a wide variety of chemical reactions. Ultimately, when presented with a given molecule, students should be able to develop a reasonable synthesis plan based on firm ideas and reliable transformations.
e-EROS gives detailed information about 4,500 reagents and catalysts, with 200 new or updated articles added each year. Articles contain preparation details, physical property information, and commentary on the role the reagent plays in organic synthetic reactions.
Along with the texts below, here are some other resources for finding information on named reactions. You can also search name reactions in Reaxys using the Query Builder (go to the Reactions section, then drag Reaction Type into the search box). Then enter the reaction name in the index and select all of the variations.
Aim of the course is to acquire knowledge and understanding, concepts and learning skills within the following domains:
1) students should learn, understand and deepen the advanced principles which connect the structure of organic compounds with their physicochemical properties, related to organic reactivity;
2) students should learn, understand and deepen the principles underlying advanced organic reactions allowing them to rationally interpret reaction mechanisms and to understand similarities and differences among different reaction pathways;
3) students should learn and understand close connections between organic chemistry and neighboring disciplines such as biochemistry and medicinal chemistry;
4) students should select information and ideas in order to make judgments and apply such information to solve ever emerging problems of organic synthesis, to propose ways to design and synthesize simple chiral organic compounds in a stereoselctive way;
5) students should acquire learning skills and communication skills by employing appropriate language to both specialized and non-specialized audience, in line with the above mentioned objectives. At the end of the course, students having followed all the theory and exercise lessons are expected to be able to applying knowledge and understanding of the above mentioned subject areas through the correct execution of problems and exercises about:
1) recognizing and analyzing the relationship between structure and properties (reactivity) of organic molecules;
2) proposing viable solutions as how to retro-synthesize, synthesize, transform, and interconvert the above mentioned organic compounds.
The first part of the course is devoted to recall and advance knowledge acquired in the Organic Chemistry I course. Particular attention will be devoted to the topics related to the stereochemirty of organic compounds and reaction stereocontrol. The following subjects are then treated: carbon-carbon bond forming reactions; functional group interconversion, protecting group insertion and cleavage. The second part of the course allows students to acquire knowledge on stereoselective synthesis of organic compounds focusing on retrosynthetic analysis, stereoselective methodologies, and asymmetric catalysis and organocatalysis. The course will be introduced by a brief dissertation on scientific literature and bibliographic search, with a description of the main features of scientific articles that are accessible from online databases.
According to the abovementioned objectives and contents, the course is carried out through frontal oral lessons and includes exercises at the blackboard dealing with the design, synthesis, and transformation of simple organic molecules which could be connected with the pharmaceutical and biological domains. These exercises are open for free discussion between teacher and students and they are considered an essential part of the course.
The final examination consists of a written exam followed by an oral colloquium. The written exam deals with the execution of exercises on asymmetric synthesis and reactivity of organic compounds. This test is aimed at verifying whether the student has developed the skill and ability of 1) recognizing the relationship between structure and properties of organic compounds, 2) predicting the behavior of a given organic chemistry transformation among those comprised in the program, 3) selecting and deploying information from the theory study in order to furnish solutions to a given practical organic synthesis problem.
At the end of the course, the student is expected to acquire knowledge and competence on basic organic chemistry.
In particular, the student achieves the following targets:
1. knowledge of the basic functional groups and application of this knowledge for the classification of simple organic molecules;
2. knowledge, understanding and application of the structural representation of simple organic molecules and their visualization in the three-dimensional space also with the help of molecular models;
