Sulfoxide‐Controlled Stereoselective Aza‐Piancatelli Reaction
Résumé
The development of a novel stereoselective aza-Piancatelli reaction to access 4aminocyclopentenones 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 excellent drs (up to > 95:5) depending upon the furan substitution pattern.
