A simple, convenient, transition metal-free one pot synthesis of 3,5-disubstituted-1,2,4-triazoles has been established. The innovation in this reaction is the use of easily available 1,1-diaminoazines as substrates. This method provides the products with wider substrate scope, at an expedited rate, and with relatively better yields in comparison to the reported methods. The reaction mechanism involves an initial intermolecular nucleophilic addition (facilitated by I2) followed by intramolecular nucleophilic cyclization.

1,3-Dipolar cycloadditions between diethyl azodicarboxylate and the polymer-bound munchnones generated from the corresponding carboxylic acids provided a library of 3,5-disubstituted 1,2,4-triazoles in excellent yield and high purity.

A series of 3,5-diaryl-s-triazoles were synthesized and evaluated as postimplantation contragestational agents.The introduction of various substituents (e.g., an o-alkyl chain on one phenyl and a m-alkoxy group on the other) was found to increase the potency.Several compounds with very high pregnancy-terminating activity in both hamsters and rats were obtained.One of these, 3-(2-ethylphenyl)-5-(3-methoxyphenyl)-s-triazole, DL 111 (36), was selected for detailed evaluation in various animal species.A synthetic scheme for the preparation of these compounds and preliminary structure-activity relationships are presented.
