摘要

The reaction of biphenyl acetamides with excess of oxalyl chloride/stannyl chloride offers a one pot, high-yield entry to 4, 5-dioxoaporphine alkaloids. This strategy has been applied to the synthesis of 4, 5-dioxodehydrocorydine starting from 1-iodo-2, 3-dimethoxybenzene. The cytotoxicity of tetraoxygenated 4, 5-dioxoaporphines has been evaluated.
