cascade reaction between α-substituted acroleins, nitroalkanes, and paraformaldehyde that proceeded smoothly to give high yields of functionalized δ-lactols under mild conditions, is described. This methodology is useful in the development of a concise synthetic route to natural products (±)-manzacidin A and C. multicomponent reaction - α-substituted acroleins - 1,8-diazabicyclo[5.4.0]undec-7-ene - δ-lactols
描述了在温和的条件下,α-取代的丙烯醛,硝基烷和多聚甲醛之间的碱催化多组分级联反应,该反应平稳进行,可得到高产率的官能化δ-内酯。此方法可用于开发从简明的合成路线到天然产物(±)-山梨酸A和C的方法。 多组分反应-α-取代的丙烯醛-1,8-二氮杂双环[5.4.0]十一碳-7-烯-δ-内酯
