Book 1997with the aid of - heterocycles. A wide range of modern methods and strategies for the construction and synthetic elaboration of versatile heterocycles is surveyed in depth by leading researchers in this field. Due to the high quality and up-to-date coverage of each chapter, this volume provides a va

Using ring-opening reactions of oxabicyclic compounds as a strategy in organic synthesis,s of these substances. Methods to desymmetrize . oxabicyclic compounds are also presented. The utility of these substrates for organic synthesis is demonstrated by the many strategies available for ring-opening the bicyclic compounds to yield cyclic and acyclic structures. Examples demonstrating how

The nucleophilic addition/ring closure (NARC) sequence for the stereocontrolled synthesis of hetero for the synthesis of heterocyclic compounds. A heavy emphasis is placed on the stereoselectivity associated with such syntheses. After an introductory section the material is organised into a series of sections based on different classes of nucleophiles. The first (and major) section deals with nuc

Chiral acetylenic sulfoxides and related compounds in organic synthesis, (1), vinyl sulfoxide (2), acetylenic sulfinate (3), acetylenic sulfonate (4), and l-propene-l, 3-sultone (5) are developed. Their applications in Diels-Alder reactions, heterocycle and alkaloid syntheses are also investigated. For the chiral acetylenic sulfoxide, the sulfoxide moiety not only enabl
