Abstract

Under the mild conditions, reductive cyclizations of 2-nitrobenzaldehydes or 2’-nitroacetophenone towards 2,1-benzisoxazoles were accomplished in the presence of 2-bromo-2-nitropropane/Zn in methanolic solution. The synthetic utility and the role of 2-bromo-2-nitropropane were investigated.
