The addition reactions of chlorosulfonyl isocyanate (CSI) to N-phenylmaleimide and 2-phenyl-3a,4,7,7a-tetrahydro-1H-isoindole-1,3(2H)-dione were investigated. Interesting products were obtained from the reaction of both compounds with CSI. N-phenylmaleimide led to the formation of an electrophilic substitution product, 4-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)benzenesulfonyl chloride while 2-phenyl-3a
研究了氯磺酰基异氰酸酯(CSI)与N-苯基马来酰亚胺和2-苯基-3a,4,7,7a-四氢-1 H-异吲哚-1,3(2 H )-二酮的加成反应。从这两种化合物与 CSI 的反应中获得了有趣的产物。N-苯基马来酰亚胺导致形成亲电取代产物 4-(2,5-dioxo-2,5-dihydro-1 H -pyrrol-1-yl)benzosulfonyl chloride 而 2-phenyl-3a,4,7, 7a-tetrahydro-1 H -isoindole-1,3(2 H )-dione 导致形成 ((3a S ,7a R,E )-3-oxo-2-phenyl-2,3,3a,4, 7,7a-hexahydro-1 H-isoindol-1-ylidene) 氨磺酰氯。两种产物的结构均通过核磁共振和质谱等光谱方法确定。进行了理论研究以解释具有相似结构的两种化合物的不同反应。通过理论研究确定,两
