benzene to afford the corresponding E-2-phenyliodonio tosylate in good yield. This new alkenyl iodonium salt upon reaction with various nucleophiles offers an easy access to substituted enamine derivatives of crotonic acid. The reaction can be also extended to N-substituted crotonates.
3-氨基巴豆酸甲酯与[羟基(甲苯磺酰氧基)碘]苯反应,以高收率得到相应的E -2-苯基碘代甲苯磺酸甲苯酯。与各种亲核试剂反应后,这种新的烯基碘鎓盐可轻松获得巴豆酸的取代烯胺衍生物。该反应还可以扩展至N-取代的巴豆酸酯。
