Abstract

This paper reports a method for highly enantioselective Diels-Alder reaction with an acetylene equivalent to produce chiral-bridged dienes. These dienes, by coordination to Rh(I), can serve as catalysts for the enantioselective addition of vinyl or aryl groups to alpha,beta-unsaturated ketones.
