Cationic Oxazaborolidine Catalyzed Enantioselective Diels-Alder Reaction of α,β-Unsaturated Acetylenic Ketones
[Image: see text] Cationic oxazaborolidine 1 affords Diels-Alder adducts of α,β-unsaturated acteylenic ketones with cyclic and acyclic dienes in excellent yields and enantioselectivities. Importantly, dienophiles lacking the typical hydrogen bonding motif as required for other oxazaborolidinium medi...
