  Cooperative, Highly Enantioselective Phosphinothiourea Catalysis of Imine−Allene [3 + 2] Cycloadditions

  摘要：

  A new family of phosphinthiourea catalysts was developed for the highly enantioselective synthesis of 2-aryl-2,5-hydropyrroles via a [3 + 2] cycloaddition of an electron-deficient allene with aryl and heteroaryl diphenylphosphinoylimines. The presence of both H(2)O and Et(3)N as additives was found to be important for achieving optimal rates. Dual activation of both nucleophile and electrophile by the bifunctional catalyst is invoked to account for the observed high reactivity and enantioselectivity.

  [reaction: see text] The enantioselective borodeuteride reduction catalyzed by optically active beta-ketoiminato cobalt complexes was applied to N-(di(o-tolyl)phosphinyl)aldimines to afford the corresponding optically active deuterated primary amines in high yields with high enantiomeric excesses after simple deprotection. The present deuteride reduction of aldimines is in the opposite sense of the enantioselective

  日期：2016.5

  A dual catalyst system using THT-based chiral sulfide 2a and H-bond donor 10a was developed for the asymmetric imino Corey-Chaykovsky reaction. Under the optimum reaction conditions, cinnamyl bromide reacted with a wide scope of N-diphenylphosphinic aldimines, to give the major trans-aryl cinnamyl aziridines with up to 98% ee. The role of H-bond donor 10a was demonstrated empirically as well. (C) 2014 Elsevier Ltd. All rights reserved.

  日期：2001.2

  The addition of dialkylzinc reagents to N-(diphenylphosphinoyl) imines is a convenient method for the preparation of optically enriched amines. Herein we present our most recent results on this reaction, including solvent effects on the enantioselectivity and the extension of this method to a variety of N-(diphenylphosphinoyl) imines.
