  A new class of nonhormonal pregnancy-terminating agents. Synthesis and contragestational activity of 3,5-diaryl-s-triazoles

  摘要：

  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.

  A number of symmetrical 3,5-disubstituted-4H-1,2,4-triazoles have been synthesized in good yields by deamination of the corresponding 4-amino-1,2,4-triazoles via reductive diazotation of these amino compounds in the presence of hypophosphorous acid. Analytical, spectral data and theoretical calculations confirmed the structures of the new triazole derivatives.

  Via a one-pot process, catalyzed by Cu(OAc)(2), a series of 3,5-disubstituted 4H-1,2,4-triazoles was conveniently and efficiently synthesized by using low-toxicity, stable, readily available, inexpensive amidine hydrochloride.
