A novel one-pot three-component reaction for the synthesis of multisubstituted furo[3,2-c]chromenes using 3-(1-alkynyl)chromones, aryl iodides, and alcohols is developed via Pd-catalyzed cascade 1,4-addition and cyclization. This synthetic approach efficiently generates two C–O bonds and one C–C bond to construct diverse furo[3,2-c]chromenes structures.
通过钯催化的级联1,4-加成反应,开发了一种新颖的一锅三组分反应,该反应可使用3-(1-炔基)色酮,碘代芳基和醇类合成多取代的呋喃并[3,2- c ]色烯。和环化。这种合成方法可以有效地产生两个C–O键和一个C–C键,以构建不同的呋喃[3,2- c ]苯二甲基结构。
