摘要：

(Chemical Equation Presented) In full control: A regio- and stereoselective cross-coupling reaction between internal alkynes and imines that provides selective access to allylic amines and γ-lactams has been developed (see scheme). This intermolecular [2+2+1] process could be described as an alkoxide-directed aza-Pauson-Khand-like annulation. The alkyne can tolerate a wide range of substituents R3. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
