Abstract

Abstract: The construction of the pyrrolidine ring about a nitrogen of a primary amine by a reductive condensation reaction using 2, 5-dimethoxytetrahydrofuran and sodium borohydride in acidic water medium is described. The reaction is fast, affords good to excellent yields and appears insensitive to electron effects and severe steric hindrance; it is found to be compatible with a large variety of aryl substituents, including nitro and oxo ...
