Abstract Copper-catalyzed aerobic methyl/methylene oxygenation of substituted indoles and pyrroles was developed using 1,4-diazabicyclo[2.2.2]octane (DABCO) as an additive in dimethyl sulfoxide (DMSO). Similar aerobic catalytic conditions could also be utilized for direct C–H formylation of C(3) on indoles and C(2) on pyrroles.

摘要 使用1,4-二氮杂双环[2.2.2]辛烷(DABCO)作为二甲基亚砜(DMSO)的添加剂,开发了铜催化的取代吲哚和吡咯的甲基/亚甲基氧合反应。类似的有氧催化条件也可以用于吲哚的C(3)和吡咯的C(2)的直接C–H甲酰化。 使用1,4-二氮杂双环[2.2.2]辛烷(DABCO)作为二甲基亚砜(DMSO)的添加剂,开发了铜催化的取代吲哚和吡咯的甲基/亚甲基氧合反应。类似的有氧催化条件也可以用于吲哚的C(3)和吡咯的C(2)的直接C–H甲酰化。
