A simple method to polyhydroxylated olefinic molecules using ring-closing olefin metathesis

Abstract

This paper describes the ring-closing metathesis of silyl ether connected dienes using molybdenum and ruthenium alkylidene catalysts. The cyclizations proceed to afford the corresponding cyclic silyloxy olefins in good to excellent yields. Subsequent oxidative ring cleavage yields highly functionalized olefins.
