Annual reports in organic synthesis 1995 [antikvár]

PREFACE One of the most difficult problems facing chemists today is that of "keeping up with the literature." For several reasons, the problem is particularly severe for the synthetic organic chemist. Bits of information of potential use are scattered throughout common chemistry journals and can be found in any paper, not just those dealing strictly with synthesis. Thus, synthetic chemists must read a large number of journals and must organize and index what they read to make the information available for future reference. All synthetic chemists do this, but the task is becoming more difficult each year as the flow of information increases. The problem, however, is shared to some extent by all. Most organic chemists are at some time faced with the problem of synthesizing a desired material, and for many the problems are formidable. Non specialists faced with the synthetic problem are not likely to have kept pace with the developments in synthetic chemistry that may well solve their problems, and they will not have the necessary information in their files. Thus, we felt that an organized annual review of synthetically useful information would prove beneficial to nearly all organic chemists, both specialists and non specialists in synthesis. It should help relieve some of the information storage burden of the specialist and should enable the non specialist who is seeking help with a specific problem to rapidly become aware of recent synthetic advances. Ideally also, it should appear as promptly as possible after the close of the abstracting period. As in the past years, we have placed particular emphasis on keeping the abstracts as concise as possible, while indicating the generality of the reactions involved. We have tried to combine similar publications into inclusive abstracts. This practice has allowed us to include a larger number of references without a substantial increase in the book's length. It should be noted that where multiple references are included in the abstract, the first mentioned refers to the equation presented. The remaining references are similar but not identical. To further aid the readers, we have tried to separate less similar references from those represented by the graphic by the phrase "see also:". We have allowed for two such separations per graphic. The year has omitted from each reference as presumably all are from 1994. Any references from
