    摘要: Antibacterial 2-ethyl-1-pyrroline-3-carboxamides and derivatives thereof are prepared from either 1-(2-propynyl)-2-pyrrolidinone or 1-(1,2-propadienyl)-2-pyrrolidinone and amines in the presence of base. The carboxamides react with phenyl isocyanates to produce 1-phenylcarbamyl-2-ethyl-2-pyrroline-3-carboxamides, with either an acid halide or acid anhydride to give the corresponding 1-acyl-2-ethylidenepyrrolidine-3-carboxamides and with hydrogen to give the corresponding 2-ethyl-pyrrolidine-3-carboxamides.

    摘要: The present invention provides methodology for carbon-nitrogen bond formation via vinyl or aryl amination. In the process of the invention, an sp2 hybridized radical is reacted with an azomethine moiety to form pyrrolidine and indole compounds. The methodology provides a facile process for the synthesis of compounds having the pyrrolidine or indole subunit and is especially advantageous for compounds having acid or base labile functional groups andor is comprised of chiral centers susceptible to acidbase epimerization.
