Ring-Closing Metathesis of Functionalized Acetylene Derivatives: A New Entry into Cycloalkynes.

Abstract

A tungsten alkylidyne catalyst is the key to achieving ring-closing metatheses of diynes to form functionalized macrocycles [Eq. (a)]. Partial reduction of the cycloalkynes provides stereoselective Z-configured cycloalkenes, which are currently inaccessible by conventional alkene metathesis. © 1998 WILEY-VCH Verlag GmbH, Weinheim, Fed.
