  Two Efficient Cascade Reactions to Synthesize Substituted Furocoumarins

  摘要：

  We have developed two efficient one-pot reactions to generate furo[3,2-c]coumarins and chlorofuro[3,2-c]coumarins through addition/cyclization/oxidation and chlorination. One cascade addition/cyclization/oxidation sequence of 1 with H2O in the presence of 20% CuCl as Lewis acid under an air atmosphere generated the 2-substituted-4H-furo[3,2-c]chromen-4-one 2. Another sequence in the presence of 10% CuBr and excess CuCl2 as the oxidant afforded the 3-chloro2-substituted-4H-furo[3,2-c]chromen-4-one 3.

  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。
