Abstract

The bisthiadiazolines 4a–4g have been synthesized in good yields from the cyclization reactions of bisthiosemicarbazones 3a–3g with acetic anhydride. The condensation reaction of dibenzaldehydes 2a–2g with thiosemicarbazide in alcoholic medium provided 3a–3g and former were obtained from the O-alkylation of 3-hydroxybenzaldehyde with suitable 1, ω- dibromoalkanes under alkaline conditions in the presence of dry EtOH/DMF. The ...
