The oxidation of 3-R-1,5-dihydro-2,4-benzothiepines with m-chloroperbenzoic acid occurs in a highly diastereoselective fashion. The resulting trans-sulfoxides at -60 degreesC in CDCl3 exist as an equilibrium mixture of the chair and boat forms with the substituents in the equatorial position. The fraction of the boat conformation increases in the series R = Ph, Me, t-Bu.
