  • Title: Catalytic asymmetric synthesis of α,β-disubstituted α,γ-diaminophosphonic acid precursors by Michael addition of α-substituted nitrophosphonates to nitroolefins.
    Author: Tripathi CB, Kayal S, Mukherjee S.
    Journal: Org Lett; 2012 Jul 06; 14(13):3296-9. PubMed ID: 22702411.
    Abstract:
    Michael additions of α-substituted nitrophosphonates to various nitroolefins are shown to proceed with high diastereo- and enantioselectivity when catalyzed by a quinine-derived thiourea-tertiary amine bifunctional catalyst and generate α,γ-diaminophosphonic acid precursors with contiguous quaternary and tertiary stereocenters.
