Is it possible to have access to all stereoisomers if you begin your synthesis with only one single starting material? This book shows ways and concepts how this can be achieved by using the right reagents, conditions or reaction sequences. Especially if the starting material is very cheap or readily available this approach has a very high value in academia and industry for example to build up a new compound library. This unique textbook presents numerous examples of this so-called "directed selectivity" which are often hidden in the original literature. Highly useful for every organic chemistry student.
