Abstract Peroxidase or light catalysed oxygenation of 2′,4-dihydroxy-4′-methoxychalcone produced two labile initial products characterized as stereoisomers of 4′-hydroxy-6-methoxy-2-(α-hydroperoxybenzyl) coumaranone. By analogy, the products from similar oxygenation reactions of 2′,4,4′-trihydroxychalcone previously studied are now considered to be hydroperoxy-benzylcoumaranones rather than dioxetanes
摘要 过氧化物酶或 2',4-二羟基-4'-甲氧基查尔酮的光催化氧化产生两种不稳定的初始产物,其特征为 4'-羟基-6-甲氧基-2-(α-氢过氧苄基)香豆酮的立体异构体。以此类推,之前研究的 2',4,4'-三羟基查尔酮的类似氧化反应的产物现在被认为是氢过氧苄基香豆酮而不是二氧杂环丁烷。
