An efficient domino process for the construction of 2,3-disubstituted benzo[b]furans has been developed viacopper-catalyzedthree-componentcouplingreactions of salicylaldehydes, amines, and alkynes followed by base-assisted O-annulation reaction.
通过铜催化的水杨醛,胺和炔烃的三组分偶联反应,然后进行碱辅助的O型环化反应,已经开发出了一种高效的多米诺方法,用于构建2,3-二取代的苯并[ b ]呋喃。
