摘要:
Starting from 2,3-dihydro-1,5-benzothiazepin-4-amine (1) tricyclic 1,5-benzothiazepines were obtained. Reaction with ethyl bromopyruvat and ethyl aminoacetate hydrochloride led to the imidazo[2,1-d][1,5]benzothiazepines 3 and 6, respectively. The triazolo derivative 8 was prepared by treatment of 1 with triethyl orthoacetate/ammonia, followed by oxidative cyclization with sodium hypochlorite.
