  Research Article: Asymmetric Hydrophosphylation of Chiral N-Phosphonyl Imines Provides an Efficient Approach to Chiral α-Amino Phosphonates

  摘要：

  Chiral N‐phosphonylimines were found to react with lithium phosphites to provide various substituted chiral α‐amino phosphonates in excellent yields (94–97%) and diastereoselectivities (93:7–99:1). The types of bases utilized for generating the nucleophile are crucial for the effectiveness of asymmetric induction. In addition, N,N‐isopropyl group on chiral N‐phosphonylimine auxilliary was proven to be superior to other protecting groups in controlling diastereoselectivity. The absolute configuration was unambiguously determined by converting a chiral α‐amino phosphonate into its authentic N‐Cbz derivative.

  日期：——

  The enantioselective hydrophosphonylation of N-Boc imines was investigated using a new family of pseudo-symmetric guanidine–thiourea catalysts, providing α-amino phosphonates in moderate to high yields with good enantioselectivity. The catalyst was heterogenized by polymerization with styrene and the resulting catalyst was applied to reactions under continuous-flow conditions.
