✦ Synopsis

Abstract

An improved synthesis for the preparation of 3‐oxo‐1,2,5‐thiadiazolidine 1,1‐dioxides has been developed. This facile two‐step procedure fromα‐amino acid esters and chlorosulfonyl isocyanate results in excellent yields of products.

## Abstract A number of symmetrical 3,5‐disubstituted‐4__H__‐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
