The first successful enantioselective hydrosilylation of cyclic imines promoted by a chiral zinc complex is reported. In situ generated zinc-ProPhenol complex with silane afforded pharmaceutically relevant enantioenriched 2-aryl-substituted pyrrolidines in high yields and with excellent enantioselectivities (up to 99% ee). The synthetic utility of presented methodology is demonstrated in an efficient synthesis of the corresponding chiral cyclic amines, being pharmaceutical drug precursors to the Aticaprant and Larotrectinib.

Page/Page column 61, (2011/09/19)
The present invention provides a highly efficient, versatile one-step process for asymmetric synthesis of either diastereomer of 2-substituted pyrrolidines from a single starting material with excellent yields and high diastereoselectivety. Also provided is a method for the asymmetric synthesis of both diastereomers of 2-substituted piperidines with good yields and excellent diastereoselectivety. Diasteroselectivity is controlled effectively by choice of reducing agent.
