摘要:

开发了一种新的由锰[Mn(Ⅲ)/Mn(Ⅱ)]催化1-异腈基-2-[1-(三氟甲基)乙烯基]苯与芳基硼酸的自由基 6-endo-trig环化反应. 该反应条件温和, 可在没有任何外部氧化剂、 配体或添加剂的情况下, 得到各种高区域选择性和化学选择性的4-三氟甲基-2-芳基喹啉衍生物.

关键词: 三乙酰丙酮锰诱导, 异腈, 苯硼酸, 4-三氟甲基喹啉

Abstract:

A new Mn(Ⅲ)/Mn(Ⅱ) induced reaction was developed, which involves a radical 6-endo-trig cyclization of 1-isocyano-2-[1-(trifluoromethyl)vinyl]benzene with arylboronic acid and catalyzed by manganese. Various 4-CF3-2 arylquinolines were obtained with high regioselectivity, chemical selectivity and mild condition without any external oxidants, ligands, or additives.

Key words: Mn(acac)3 induced, Isonitrile, Boronic acid, 4-CF3-quinolines
