Regio- and Stereoselective Direct Cross-Coupling of Aromatic Imines with Allenic Alcohols

Abstract

We describe a titanium-mediated reaction for the convergent coupling of allenic alcohols with aromatic imines. Overall, the bond formation occurs at the central carbon of the allene, proceeds with net allylic transposition, and provides substituted 1,3-dienes bearing allylic amine functionality in a regio- and stereoselective fashion.
