Grubbs cross-metathesis pathway for a scalable synthesis of γ-keto-α,β-unsaturated esters

J Org Chem. 2014 Feb 7;79(3):1467-72. doi: 10.1021/jo4023606. Epub 2014 Jan 21.

Abstract

A direct and scalable route to γ-keto-α,β-unsaturated esters, useful intermediates in medicinal chemistry and natural products synthesis, is reported. The key step involves the use of Grubbs' second-generation olefin metathesis catalyst for cross-metathesis of alkyl acrylates and 2° allylic alcohols. The metathesis step is followed by oxidation to give the desired products in high yield on scales of up to 25 g.
