[2.2.3]Cyclazines are obtained in moderate yields by reaction of 3H-pyrrolizines bearing conjugative substituents (Ph or CO2Me) with vinamidinium salts in the presence of strong bases. Syntheses of the previously unknown 2-phenyl-3H-pyrrolizine and 1-methoxycarbonylcyclopenta [h] [2.2.4] cyclazine are also described.
[2.2.3]通过在强碱的存在下,通过带有共轭取代基(Ph或CO 2 Me)的3H-吡咯嗪与vinamidinium盐的反应,可以以中等收率获得环嗪。还描述了以前未知的2-苯基-3H-吡咯嗪和1-甲氧基羰基环戊[h] [2.2.4]环嗪的合成。
