Solid state photochemical reaction of achiral N-(β,γ-unsaturated carbonyl)thiocarbamate to optically active thiolactone in the chiral crystalline environment

Abstract

O-Methyl N-(2,2-dimethylbut-3-enoyl)-N-phenylthiocarbamate crystallized in the chiral space group P2₁, and the solid state photoreaction initiated intramolecular [2+2] thietane formation followed by rearrangement, leading to optically active γ-thiolactone.
