A new synthetic approach toward the synthesis of flavones and pyranoflavone has been developed by light induced intramolecularphotochemicalWittigreaction in water onto aryloxycarbonyl groups and suitably substituted phosphonium bromides sans any phase transfer catalyst or promoter.
朝向黄酮和pyranoflavone的合成的新的合成方法已被开发通过光诱导的分子内光化学维悌希反应在水到芳氧基羰基和适当取代的鏻溴化物SANS任何相转移催化剂或助催化剂。
