  Asymmetric synthesis of indolo[2,3-a]quinolizidin-2-ones - congeners to yohimbine-type alkaloids

  摘要：

  Schiff bases derived from tryptophan methyl ester and tryptamine react with Danishefkys diene in the presence of ZnCl2 to give enaminones which are subsequently transformed into indolo[2,3-a]quinolizidin-2-ones by acid-catalyzed cyclization. These tetracyclic aminoketones serve as viable intermediates in the construction of complex alkaloids, e. g. reserpine and deserpidine, and analogues thereof.
