The reaction of propargylic alcohols with diaryl disulfides and carbon monoxide in the presence of tetrakis(triphenylphosphine)palladium leads to a novel thiolative lactonization to afford β-(arylthio)-α,β,-unsaturated lactones in moderate to good yields.

A series of β-chalcogeno-α, β-unsaturated chalcogenoesters (1 and 2) were synthesized, and their molecular structures were investigated in detail by X-ray crystal analyses. Interestingly, intramolecular interactions between the carbonyl oxygen and the chalcogen atom at the β-position (β-S ...O and β-Se...O) were observed in most cases, and intermolecular π-π interaction and hydrogen bonding were observed in the case of δ-hydroxy derivatives (1b and 2b).
