Total Synthesis of Natural p-Quinol Cochinchinenone

Cochinchinenone has been synthesized in only five steps and four pots and in 58% overall yield from commercially available 2,3-dimethoxy-4-hydroxy-benzaldehyde and OPMB-protected p-hydroxy acetophenone, the key step being the oxone-mediated oxidative dearomatization of the corresponding ketone-containing p-substituted phenol.
