Book excerpt: Bicyclo[1.1.1]pentanes (BCPs) gained interest in material sciences and as non-classical bioisosteres for para-substituted benzenes, alkynes and tert-butyl groups in drug design. The synthesis of BCPs is still challenging and limits their application. Starting from the strained [1.1.1]propellane there have been many contributions using CC and CN bond formations to obtain BCPs. The CS bond formation has been rarely used and not systematically investigated. Therefore, this thesis aimed at the development of methods to obtain BCP sulfides and related structures from [1.1.1]propellane. The obtained BCP sulfides were oxidized and iminated to obtain BCP sulfoxides and sulfoximines. These modifications to tune parameters like the polarity are important for a successful application of the structural motif in drug design. The final aim of this thesis was the synthesis and application of a bench-stable BCP building block to facilitate the use in medicinal chemistry and other fields. A facile and scalable four-step route to sodium BCP sulfinate was developed to deliver the product in good yield and purity. The sulfinate was applied in the synthesis of BCP sulfones, sulfoxides, a sulfinamide and sulfonamides.

Available in PDF, EPUB and Kindle. Book excerpt: Domino reactions enable you to build complex structures in one-pot reactions without the need to isolate intermediates- a dream comes true. In this book, the well-respected expert, Professor Lutz Tietze, summarizes the possibilities of this reaction type - an approach for an efficiant, economically benificial and ecological benign synthesis. A definite must for every organic chemist.

Download or read book Side Reactions in Organic Synthesis written by Florencio Zaragoza Dörwald and published by John Wiley & Sons. This book was released on 2006-03-06 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most syntheses in the chemical research laboratory fail and usually require several attempts before proceeding satisfactorily. Failed syntheses are not only discouraging and frustrating, but also cost a lot of time and money. Many failures may, however, be avoided by understanding the structure-reactivity relationship of organic compounds. This textbook highlights the competing processes and limitations of the most important reactions used in organic synthesis. By allowing chemists to quickly recognize potential problems this book will help to improve their efficiency and success-rate. A must for every graduate student but also for every chemist in industry and academia.
