摘要:
取代的吡啶鎓盐与 E-1,2-二(烷基磺酰基)-1,2-二氯乙烯的反应进行得非常专一。在三倍过量的 Et3N 存在下,在氯仿中加热这些试剂,可以高产率地得到取代的 1,2-二(烷基磺酰基)吲嗪类化合物。包括 X 射线衍射在内的物理化学方法证实了反应产物的结构。

The reactions of substituted pyridinium salts with E-1,2-di(alkylsulfonyl)-1,2-dichloroethenes proceed regiospecifically. Heating of these reagents in chloroform in the presence of a threefold excess of Et3N affords substituted 1,2-di(alkylsulfonyl)indolizines in high yields. The structures of the reaction products were confirmed by physicochemical methods, including X-ray diffraction.
