Stereoselective synthesis of (−)- and (+)-pentenomycins using RCM
摘要:
An efficient synthesis of enantiopure (-)- and (+)-pentenomycins are described by reductive iodo elimination and ring-closing metathesis (RCM), as the key steps. The first synthesis of the unnatural (+)-isomer is described. (C) 2003 Elsevier Science Ltd. All rights reserved.

A versatile and stereoselective totalsynthesis of (+) and (-) pentenomycin I, (+) halopentenomycins I and dehydropentenomycin from a common chiral polyhydroxylated cyclopentene through oxidation and protection/deprotection has been described. Stereoselective hydroxymethylation, stereoselective Grignard reaction and ring closing metathesis are the key features of our approach.
