  Synthesis of novel thiazoles bearing hydrazine, thiosemicarbazide, thiazole, and thiazolidinone moieties

  摘要：

  Thiazolecarboxylate esters (I) and (II) react with hydrazine hydrate to give the acid hydrazides (III) and (IV), which then react with KSCN and PhNCS to give high yields of the thiosemicarbazides (V) (VIII). Cyclocondensation of the thiosemicarbazide (V) with 3-phenyl-3-chloro-2-oxopropionic acid derivatives gives compounds with two thiazole moieties (IX)-(XIV). The reaction of the phenylthiosemicarbazides (VII) and (VIII) with chloroacetyl chloride and (or) chloroacetic acid affords the thiazolidinonethiazoles (XV) and (XVI).

  Cyclization of 2-methyl (or -phenyl)-5-phenylthiazole-4-carbohydrazides (1) and (2) under various conditions gives differing oxadiazoles: 2-(2'-substituted-5'-phenyl-4'-thiazolyl)-1,3,4-oxadiazole-5-thiones (7) and (8), and 2-(2'-substituted-5'-phenyl-4'-thiazolyl)-1,3,4-oxadiazoles (9) and (10). Cyclodehydration of thiazolecarbonyl-thiosemicarbazides (3)-(6) with NaOH gives the 3-(2'-substituted-5'-phenyl-4'-thiazolyl)-4-substituted-4H-5-mercapto-1,2,4-triazoles (11)-(14), while H3PO4 gives the 2-(2'-substituted-5-phenyl-4'-thiazolyl)-5-phenylamino-1,3,4-thiadiazoles (15) and (16).
