Abstract

The asymmetric Diels-Alder reactions of chiral sulfinylacrylate derivatives (1 and 2) with dienes (3-12) were examined under high-pressure (1.2 GPa) conditions. The endo cycloadduct (13e) obtained from sulfinyl acrylate (1) and 2-methoxyfuran (5) was converted to (-)-COTC (25) and (-)-gabosine C (26).
