It has been proved that the reaction between furfuryl amines and N-R-maleimides leads to the formation of aza-Michael addition products – 3-(furylmethylamino)-N-R-pyrrolidine-2,5-diones, instead of 7-oxa-2-azabicyclo[2.2.1]hept-5-enes, as this journal reported previously.
已经证明,糠醛胺与N-R-马来酰亚胺之间的反应会导致aza-Michael加成产物的形成 - 3-(糠基甲基氨基)-N-R-吡咯烷-2,5-二酮,而不是此期刊先前报道的7-氧杂-2-氮杂双环[2.2.1]庚-5-烯。
