Abstract

Lewis acid catalyzed cyclocondensation of silyloxy dienes with dieneophiles has become a powerful method of constructing complex structures in a single step.'The cyclocondensation of the appropriately substituted diene with an aldehyde or ketone provides a potentially efficient and convergent method of synthesizing a variety of Since our research group is interested in the asymmetric synthesis of y-and M a~ tones,~ we chose to investigate the ...
