Abstract

The reaction of 1-methoxymethyl-2-phenylthiocyclobutanes with phenylthiotrimethylsilane followed by hydrolysis gave (E)- and (Z)-γ,δ-unsaturated ketones with high stereoselectivity. The starting materials were easily prepared by the stereoselective addition of Grignard reagents to trans-2-phenylthiocyclobutyl ketones.
