Cyclization of 2-(furan-2-ylmethylene)hydrazinecarbothioamide (1) with ethyl 2-chloroacetate and ethyl 3-chloropropanoate in fused sodium acetate yielded 3-(furan-2-yl-methyleneamino)-2- thioxoimidazolidin-4-one (2) and 3-(furan-2-ylmethyleneamino)-2-thioxotetrahydropyrimidin-4(1H)-one (6). Treatment of 2, 6 with acetic anhydride, benzyl chloride and aromatic aldehydes furnished 1- substituted-3-(furan-2-yl-methyleneamino)-2-thioxoimidazolidin-4-one (3, 4), 1-substituted- 3-(furan- 2-ylmethyleneamino)-2-thioxotetrahydropyrimidin-4(1H)-one (7, 8), 5-arylidene-3-(furan-2-ylmethyleneamino)-2-thioxoimidazolidin-4-one(5a-c) and 5-arylidene-3-(furan-2-ylmethyleneamino)-2- thioxotetrahydropyrimidin-4(1H)-one (9a-c) respectively. The antimicrobial and CNS depressant activities of some of the synthesized compounds were studied.
