title: Enantioselective alkenylation of aldimines catalyzed by a rhodium-diene complex.
abstract: An efficient rhodium-catalyzed asymmetric addition reaction of potassium alkenyltrifluoroborates to N-nosylaldimines has been developed. Under optimal conditions, the reactions proceeded with good to excellent yields and excellent enantioselectivities (97 → 99% ee). The utility of this method is demonstrated by the formal synthesis of (-)-aurantioclavine.
