Synthesis of bicyclothiazolidinone derivatives

Research Abstract
Including synthesis of 2-hyddrazono-4-thazolidinone (1) and its reaction with aromatic aldehyde, formic acid to give triazolothiazolidinone derivatives. Also compound 1 was reacted with nitrous acid or with ethyl chloroacetate to give thiazolo[2,3-d]tetrazol-5-one and thiazolo[2,3-c]triazin-6=one
