    Synthesis of Highly Substituted Enantiopure Piperazines and Ketopiperazines from Vicinal N-Sulfinyl Diamines
    摘要:
    Enantiopure 1-benzyl-2,3-disubstituted piperazines (4) have been synthesized by treatment of N-sulfinyl-N-benzyldiamino alcohols (1) with diethyl oxalate and sodium methoxide followed by reduction with borane. Alternatively, the sulfinamido group was preserved by an N-acylation/cyclization protocol using alpha-chloroacetyl chloride that led to the synthesis of N-sulfinyl ketopiperazines (11). Ensuing elimination of the suffinyl group with NaH produced imino ketopiperazines (9) that are suitably functionalized for nucleophilic addition to the imino moiety. Stereoselective and high yielding allylation of imino ketopiperazines (9c) was achieved under Barbier conditions using CeCl3 center dot 7H(2)O as the additive.

  • Highly diastereoselective Barbier allylation and iminium cyclization: a simple entry to bicyclic and tricyclic piperazinones
    作者:A. Viso、R. Fernández de la Pradilla、A. Flores、M.A. del Águila
    DOI:10.1016/j.tet.2008.10.034
    日期:2008.12
    Barbier allylation of 5,6-dihydropyrazin-2(1H)-ones leads to a single isomer of 3 -alylpiperazin-2-ones in high yields. Further Pictet-Spengler-Grieco cyclization of 3-allylpiperazin-2-ones with aldehydes provides bicyclic and tricyclic piperazinones with high diastereoselectivity. (C) 2008 Elsevier Ltd.

    The highly diastereoselective synthesis of fused oxopiperazino-β-lactams 2 by Staudinger reaction between functionalized ketenes and 5,6-dihydropyrazin-2(1H)-ones 1 has been carried out. Further cleavage of the β-lactam ring produced 2-oxopiperazine-3-acetic acid derivatives 7 with no epimerization and in good yields.
