摘要

The total synthesis of the opioid modulator pawhuskin C has been accomplished in eight steps from methyl 3, 5-dihydroxybenzoate. The key step in this sequence is a directed ortho metalation reaction conducted without protection of a benzylic alcohol and thus presumed to involve a formal dianion intermediate.
