A practical enantioselective synthesis of massoialactone via hydrolytic kinetic resolution
摘要:
An efficient enantioselective synthesis of (R)- and (S)-massoialactone has been achieved. The key steps are the hydrolytic kinetic resolution of a racemic epoxyheptane with (R,R)-(salen)-(CoOAc)-O-III complex and ring-closing metathesis of homoallylic alcohol derived acrylate esters using Grubb's catalyst.

An asymmetricsynthesis of (S)-(+)-Massoialactone is described using the Sharpless asymmetric dihydroxylation and the regiospecific nucleophilic opening of a cyclic sulfate as key steps.

Synthesis of the esterase inhibitor valilactone (1) is reported employing the oxidation of π-allyltricarbonyliron lactone complexes with cericammoniumnitrate to afford the inherent β-lactone ring.
