摘 要: 6-甲氧基-2-(2-溴酰基)萘与硫脲反应环合得4-(6-甲氧基-2-萘基)-2-氨基噻唑;后者与水杨醛反应制备了新化合物4-(6-甲氧基-2-萘基)-2-(2-羟苄亚氨基)噻唑,收率为72.1%~94.8%。目标物采用核磁共振、红外光谱和元素分析测试技术进行了表征;分析目标物和中间体中萘环质子偶合分裂情况,并且确定了萘环上各质子的归属。 4-(6-Methoxynaphthalen-2-yl) thiazol-2-amine was first prepared from 2-bromo-1-( 6-methoxy- naphthalen-2-yl) alkyl-1-one and thiourea. 4-( 6-Methoxynaphthalen-2-yl )-2-benzylimino-thiazole was then synthesized via the reaction of 4-( 6-methoxynaphthalen-2-yl ) thiazol-2-amine with salicylal with yields of 72. 1% - 94. 8%. The structures of the compounds were determined by ^1H NMR, IR and elemental analysis. Proton assiqnment of naphthyl was performed by analyzing coupling constants of the protons on the naphthyl of target compound and intermediate.
