Heating of 3-(2-aminophenylthio)-2-methoxycarbonyl-4-methyl-2-penten-4-olide with triethylamine hydrochloride gave 3, 3-dimethyl-1H, 3H-furo[4, 3-b][1, 5]benzothiazepin-1-one. Some chemical modifications of the product including [2+2]cycloaddition and 1, 3-dipolar cycloaddition to the imino group in the product were performed.
用盐酸三乙胺加热 3-(2-氨基苯硫基)-2-甲氧羰基-4-甲基-2-戊烯-4-内酯,得到 3,3-二甲基-1H,3H-呋喃并[4,3-b][1,5]苯并硫氮杂卓-1-酮。对产物进行了一些化学修饰,包括[2+2]环加成和对产物中的亚氨基进行 1,3-二极环加成。
