The development of a stereoselective aza-Piancatelli reaction to access 4-aminocyclopentenones is reported. This transformation relies on the use of chiral o-sulfinyl anilines as chiral inductors to afford the targeted products in good to excellent yields. Remarkably, the high value-added cyclopentenones could be obtained in drs up to >95:5, depending upon the furan substitution pattern.
