(S)-(+)-2-(p-TOLYLSULFINYL)-2-BUTEN-4-OLIDE: AN ENANTIOMERICALLY PURE MICHAEL ACCEPTOR FOR ASYMMETRIC SYNTHESIS OF 3-SUBSTITUTED 4-BUTANOLIDES. (-)-PODORHIZON.

Posner, Gary H.,Kogan, Timothy P.,Haines, Stephen R.,Frye, Leah L.

, p. 2627 - 2630 (1984)

A short, reliable, and practical synthesis of (S)-(+)-2-(p-tolylsulfinyl)-2-buten-4-olide has been developed, and the utility of this Michael acceptor for highly enantiocontrolled synthesis of 3-substituted 4-butanolides has been demonstrated.
