An efficient one-pot synthesis of 2,3-diarylated benzo[b]furans was realized through the relay catalysis of N-Heterocyclic Carbene (NHC) and palladium from substituted 2′-bromodiphenylbromomethanes and aryl aldehydes. The easy availability of the starting materials, good compatibility of catalysts, convergent assembly and concomitant modification of the target scaffold, and potential utilization value
通过取代2'-溴二苯基溴甲烷和芳基醛对N-杂环卡宾(NHC)和钯的中继催化作用,实现了有效的一锅法合成2,3-二芳基苯并[ b ]呋喃。起始原料的容易获得,催化剂的良好相容性,目标支架的收敛组装和伴随的修饰以及产物的潜在利用价值,使得该策略在有机合成中具有吸引力。
