Abstract
We have synthesized a series of enamines — derivatives of 1-cyanomethyl-2-methy-enepyrrolidine-by reaction of 1-cyanomethylpyrrolid-2-one diethylacetal with compounds having a reactive methylene link. The enamines undergo a Thorpe-Zeigler cyclization in the presence of bases with the formation of pyrrolo [1,2-a]-pyrrole derivatives. The configuration of the enamines obtained were studied using PMR spectroscopy.
