Applications of the cascade cyclocarbopalladation reaction followed by Suzuki–Miyaura coupling reactions of the readily available aryl-substituted propargylic aryl ethers with arylboronic acid and potassium trans-β-styryltrifluoroborate accomplish a new versatile entry in the synthesis of benzofuran derivatives. Notably, a new approach to the challenging synthesis of C3 functionalized 2-unsubstituted
先进行级联环羰基缩合反应,然后再进行易于获得的芳基取代的炔丙基芳基醚与芳基硼酸和反式-β-苯乙烯基三氟硼酸钾的Suzuki-Miyaura偶联反应,可以实现苯并呋喃衍生物合成的新用途。值得注意的是,已经通过环碳钯/交叉偶联/芳构化方法开发了具有挑战性的C3官能化的2-未取代的苯并呋喃合成的新方法。
