Abstract

Abstract 2-Amino-4-oxo-derivatives of s-triazino [2, 1-b][1, 3] benzoxazoles, s-triazino [2, 1- b][1, 3] benzothiazoles, and s-triazino [1, 2-a] benzimidazoles were synthesized by carbonylation of 2-benzoxazolylguanidines, 2-benzothiazolylguanidines, and 2- benzimidazolylguanidines with phenyl isocyanate under microwave irradiation (180 C, 15 minutes). Using phenyl isothiocyanate instead of phenyl isocyanate under the same ...
