4-Aryl and 4-vinyl quinolines were prepared via a sequential procedure involving regioselective Rh(acac)(C2H2)/dppf-catalyzed hydroarylation/hydrovinylation of β-(2-aminophenyl)-α,β-ynones with arylboronic acids or potassium aryl and vinyl trifluoroborates, followed by nucleophilic attack of the amino group onto the carbonyl.
4-芳基和 4-乙烯基喹啉是通过连续程序制备的,涉及区域选择性 Rh(acac)(C2H2)/dppf 催化的 β-(2-氨基苯基)-α,β-ynones 与芳基硼酸或钾的加氢芳基化/氢乙烯基化芳基和乙烯基三氟硼酸酯,然后氨基对羰基进行亲核攻击。
