Foreword to second edition

Foreword to Second Edition The success of the first edition of "Organic Syntheses Based on Name Reactions and Unnamed Reactions" and the proliferation of new Name Reactions are the reason for this new revised edition. It became obvious that many new reagents and reactions are being referred to in the organic chemistry research community by their names. Hence, in addition to over 170 new reactions (previously referred to as Unnamed Reactions) in the first edition, we have included in the second edition 157 new Name Reactions bringing the total to 545. However, we have eliminated the term "Unnamed Reactions" from the title of the monograph, since these reactions are now no longer unnamed. Furthermore, we omitted some older and less utilized Name Reactions that appeared in the first edition but have included them in the Name Index, by providing reference to the page number in the first edition (e.g. Baudisch 1-27, refers to first edition, p.27). The new additions are all synthetically useful or not immediately obvious transformations. In choosing them, emphasis was placed on stereoselective or regioselective reagents or reactions including asymmetric syntheses. The latter are particularly timely with the recent Nobel Prize in Chemistry awarded in this area. Again we admit our own bias in choosing from the many interesting newer transformations reported in the literature. Where possible we have tried to consult with the Name Reaction major author. We apologize if inadvertently important reactions were omitted. We have maintained the useful format of providing important references (over 3,300); in each case this includes one of the first references to the reaction and a review reference where available. Furthermore, an example of an experimental procedure is provided. Important features of this monograph remain the indexes, which should be helpful to the reader: A names index with cross references to multiple names; A reagent index; A reaction index, e.g. acylations, asymmetric synthesis; epoxidation, heteroannulations, rearrangements, etc.; as well as A functional group transformation index, which allows one to search for conversions of one functional group to another. The latter has proved valuable to the synthetic chemist searching for pathways to perform such synthetic procedures. Hence, the monograph should be of interest to chemists in industry and academia. In fact this format has led to the monograph being adopted as a text in advanced organic chemistry courses. We thank our families for their understanding during the travail on this book and are grateful to TEVA Pharmaceutical Co. for their support.
