Abstract The α → β isomerization of hetaryl analogues of benzoins occurring in basic media on heating is a convenient preparative way to obtain hydroxymethylcarbonyl‐substituted derivatives of π‐excessive heterocycles. The reaction is favored by increased catalyst basicity, solvent polarity, and the electron‐donor ability of a hetaryl residue. At room temperature, oxidation to hetaryl analogues of
摘要 在碱性介质中加热发生的安息香杂芳基类似物的 α → β 异构化是获得 π 过量杂环的羟甲基羰基取代衍生物的一种方便的制备方法。该反应有利于增加催化剂碱性、溶剂极性和杂芳基残基的电子给体能力。在室温下,氧化为苄基的杂芳基类似物变得占主导地位。
