[en] Two efficient phase-transfer-catalyzed protocols for the diastereoselective synthesis of cis and trans isomers of 2,6-diaryltetrahydrothiopyran-4-ones (2,6-DATHTPs) have been developed. In a study of the scope of the reactions, differently substituted 2,6-DATHTPs were successfully accessed in high yields and diastereomeric excessses on both experimental and preparative scales.

Compound 1a was used as a prototypical substrate for preliminary investigations as the resulting two diastereoisomers were clearly characterized and could be separated and quantified by HPLC and NMR spectroscopy, see the Supporting Information.
