A Lewis acid dependent asymmetric Diels-Alder process in the cyclization of new chiral acrylamides with dienes

Diels-Alder cycloadditions of chiral acrylamides with cyclopentadiene proceed with high diastereofacial selectivity, giving either endo-R to endo-S products depending of the Lewis acid used.

Dual enantioselective Diels-Alder process in the cyclization of chiral acrylamide with dienes

Diels-Alder cycloadditions of chiral acrylamides with cyclopentadiene or 2, 3-dimethyl butadiene proceed with high diastereofacial selectivity. Either endo-R or endo-S products have been obtained depending upon the structures of acrylamides and Lewis acids used. The endo form was exclusively obtained over the exo form. The dependence of the mechanism of formation of opposite configurations of endo-R or endo-S products on the Lewis acids is discussed. Copyright 2004 John Wiley & Sons, Ltd.
