  A Novel Synthesis of Some New Imidazothiazole and Glycocyamidine Derivatives and Studies on Their Antimicrobial Activities

  摘要：

  5,5-diphenyl-2-thioxoimidazolidin-4-one (1) reacted with chloroacetic acid 2a and ethyl chloroacetate 2b in an alkaline medium to afford 2-(4,5-dihydro-5-oxo-4,4-diphenyl-1H-imidazol-2 ylthio)acetic acid (3a) and ethyl 2-(4,5-dihydro-5-oxo-4,4diphenyl-1H-imidazol-2 ylthio)acetate (3b), respectively. Compounds 3a,b were converted to 5,5-diphenylimidazolidine-2,4-dione (4) by boiling in ethanolic hydrochloric acid. When compounds 3a,b were treated with polyphosphoric acid, cyclization occurred, and 6,6-diphenylimidazo[2,1-b]thiazole 3,5(2H,6H)-dione (5) was obtained.2-(methylthio)-1H-imidazol-5(4H)-one derivatives (a,b reacted with hydrazine hydrate to give the corresponding hydrazones 7a,b. The reaction of 6a,b with hydrazine hydrate afforded 3-amino-2-phenylimino imidazolidin-4-one derivatives 10a,b. The antimicrobial activities of compounds 1. 3ab, 5, 7ab, and 10a,b were studied.
