2-(Bromomethyl)-1-sulfonylaziridines were converted into novel 3-sulfonamido-2,3,4,5-tetrahydro-1,5-benzothiazepines upon treatment with 2-aminothiophenol in THF in the presence of K2CO3. Starting from 3-substituted 2-(sulfonyloxymethyl)aziridines, a regio- and stereocontrolled synthesis of trans-2-phenyl- and trans-4-(phenyl or propyl)-3-sulfonamido-2,3,4,5-tetrahydro-1,5-benzothiazepines was developed
在K 2 CO 3存在下用2-氨基硫酚处理THF后,将2-(溴甲基)-1-磺酰基氮丙啶转化为新型的3-磺酰胺基-2,3,4,5-四氢-1,5-苯并硫氮杂s。从3-取代的2-(磺酰氧基甲基)氮丙啶开始,区域和立体控制合成反式-2-苯基-和反式4-(苯基或丙基)-3-磺酰胺基-2,3,4,5-四氢-根据磺酰氧基的性质,通过两种不同的反应途径以高收率开发了1,5-苯并硫氮杂s。
