, by reacting a compound of the general formula II
in which R has the meanings given above for formula I, i.e. β-vinyl ionol (formula II, R=hydrogen) or an O-protected derivative thereof (formula II, R═OH protecting group) with an oxidant in the presence of at least one transition metal, where the oxidant comprises at least one oxygen-containing compound which is selected from among hydrogen peroxide and organic hydroperoxides.
本发明涉及制备氧基乙烯基异黄酮及其式I的O-保护衍生物,其中R为氢或OH保护基,例如Si(Ra)3基团。所述制备方法是通过将一般式II的化合物与氧化剂在至少一种过渡金属的存在下反应来实现的,其中R具有上述式I中给出的含义,即β-乙烯基异黄酮(式II,R=氢)或其O-保护衍生物(式II,R=OH保护基),所述氧化剂包括至少一种含氧化合物,所述氧化合物从过氧化氢和有机过氧化物中选择。
