    Asymmetric Preparation of New N,N-Dialkyl-2-amino-1,1,2-triphenylethanol Catalysts and a Kinetic Resolution in the Addition of Diethylzinc to Flavene-3-carbaldehydes
    摘要:
    Enantiopure N,N-dialkyl-(S)-2-amino-1,1,2-triphenylethanols were prepared using a new synthetic methodology and tested for their ability to catalyze the enantioselective addition of diethylzinc to aldehydes. The structural modification of N- substituents of the catalysts led us to identify N- methyl- N-(S)-1-phenylethyl-substituted 4d as an effective catalyst for the addition. Also disclosed is a kinetic resolution of racemic flavene-3-carbaldehydes with the chiral catalyst.

  • Dynamic resolution of α-halo chiral esters for the synthesis of 3-substituted piperazin-2-ones
    作者:Jung In Jang、Seock Yong Kang、Kyoung Hee Kang、Yong Sun Park

    Dynamic resolution of α-halo esters derived from five chiral alcohols has been investigated in nucleophilic substitution with ethylenediamine nucleophiles. Stereoselective substitution of α-halo esters and following spontaneous cyclization provide a practical protocol for asymmetric syntheses of 3-substituted piperazin-2-ones up to 94:6 er.
