摘要

Abstract A series of new pyrroline I-oxides and their related pyrrolines is described. Preparation of these compounds by reductive cyclization of y-nitro carbonyl compounds is discussed. This method is critically dependent on the reducing agent in the preparation of pyrroline 1-oxides and various procedures are assessed. Zinc in aqueous ammonium chloride is successful only in the formation of 2-aryl-5, 5-dimethyl-substituted pyrroline 1- ...
