摘要

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.
