Article abstract of DOI:10.1246/cl.1981.1621

Asymmetric synthesis of β,β-disubstituted γ-butyrolactones was carried out in highly stereoselective and predictable way, by means of sequential dialkylation of (S)-γ-trityloxymethyl-γ-butyrolactone followed by lactone carbonyl transposition.Application t
