Dess–Martin Periodinane (DMP) mediated oxidative rearrangement reaction was uncovered. The reaction proceeds via oxidation of a β-hydroxy thioester to a β-keto thioester, followed by an α-hydroxylation and then further oxidation to form a vicinal thioester tricarbonyl. This product then rearranges, extruding CO2, to form an α-keto product. The mechanism of the rearrangement was elucidated using 13C labelling

A highlyenantioselective aldol-type reaction forming various β-hydroxy carbonyl compounds from 3-acetylthiazolidine-2-thione and achiral aldehydes is achieved via divalent tin enolate employing chiral diamine derived from (S)-proline as a ligand.
