(Chemical Equation Presented) A short and efficient, high-yielding enantioselective total synthesis of the marine natural product (-)-curcuquinone 1 is reported involving a regioselective [3 + 2 + 1]-benzannulation reaction as the key step. Additionally, this strategy allows the isolation of curcuhydroquinone monomethyl ether 9 as an intermediate of the benzannulation reaction and its subsequent further protection toward diversified hydroquinones.
