A synthesis of (-)-curcuphenol, (-)-curcuquinone and (-)-curcuhydroquinone from o-valerolactone is described. The key steps include an Evans asymmetric methylation of 5-(benzyloxy)pentanoic acid (5), an oxidative aromatization of enone (11) and a regioselective oxidation of the phenol to o-quinone derivative with bis(trifluoro acetate)iodobenzene.
本研究描述了从邻戊内酯合成(-)-葫芦酚、(-)-葫芦醌和(-)-葫芦氢醌的过程。关键步骤包括 5-(苄氧基)戊酸 (5) 的伊万斯不对称甲基化、烯酮 (11) 的氧化芳香化以及用双(三氟乙酸)碘苯将苯酚氧化成邻苯醌衍生物的区域选择性氧化。
