The synthesis of all four regioisomers of fused pyrrolidino-pyridines in a one-pot two-step sequential Ugi-inverse electron demand Diels–Alder reaction is described. Fused pyrrolidino-pyrazines, pyrrolidino-pyrimidines and azepinone pyridines can also be obtained in consecutive synthetic sequences.
描述了在一锅两步连续的Ugi逆电子需量Diels-Alder反应中稠合的吡咯烷基-吡啶的所有四个区域异构体的合成。熔融的吡咯烷基-吡嗪,吡咯烷-嘧啶和a庚酮吡啶也可以以连续的合成顺序获得。
