Significance

A one-pot domino cross-meta­thesis/imine allylation gives a useful alternative to multi-step syntheses of homoallylic amines. By using a chiral allylsilane, the amine products are produced in high diastereoselectivities and enan­tioselectivities. A three-step, one-pot procedure has also been developed to make substituted piperidines.
