Deoxygenative dual CO2 conversions: methylenation and switchable N-formylation/N-methylation of tryptamines

The unprecedented one-pot synthesis of N -formyl/ N -methyltryptolines from tryptamines was achieved via phenylsilane-assisted deoxygenative dual CO 2 conversions. Each of two CO 2 molecules acted as different synthons and was converted into methylene...
