Synthesis of Novel Triazolyl-substituted Carboxylic Acid Esters and Their Aminolysis

详细

Recyclization of 4-oxo-1,3-benzoxazinium perchlorates under the action of hydrazinobenzoic acids gave previously unknown 1,2,4-triazolylbenzoic acids which were esterified to obtain the corresponding esters. Alkylation of 3-(o-hydroxyphenyl)-1,2,4-triazoles with ethyl chloroacetate formed ethyl triazolylacetates, whose aminolysis allowed synthesis of novel bis-heterocyclic imides.
