The enaminones, generated from derivatives of appropriately substituted Baylis-Hillman adducts of 3-isoxazolecarbaldehydes, undergo intramolecular ring-closure reactions to afford substituted 2-pyrrolidinones, 1,5-dihydro-2-pyrrolones, and N-substituted pyrrolidines in good yields.
由3-异恶唑甲醛的适当取代的贝利斯-希尔曼加合物的衍生物生成的烯胺酮,会发生分子内环合反应,以良好的产率得到取代的2-吡咯烷酮、1,5-二氢-2-吡咯酮和N-取代的吡咯烷。
