  哈格曼酯的碱介导有氧氧化：C-1 和 C-3 位的竞争性羟基化

  摘要：

  哈格曼酯和亲电试剂的反应理论上可以发生在 C-1、C-3、C-5 和 C-2' 位置（图 1）。然而，作为一个例子，已普遍接受烷基化的位点偏好是C-3，得到的C-3-烷基衍生物通常伴随有少量的C-1-烷基产物。

  The invention provides a process for producing a chroman compound represented by formula (1), characterized in that the process includes allowing a phenol, an unsaturated compound, and a formaldehyde to react in the absence of catalyst and in the presence of water in an amount by mole 1 to 10 times that of the phenol. According to the present invention, a high-purity chroman compound can be produced in the absence of catalyst and under mild conditions. In addition, the invention provides an industrial means for producing the compound, without using a large amount of an acid or a base serving as a reaction promoter or a catalyst, which would otherwise cause side reactions, apparatus corrosion, etc.

  本发明提供了一种生产由式（1）表示的色酮化合物的方法，其特征在于，该方法包括在水的存在下，使酚、不饱和化合物和甲醛在无催化剂存在下反应，其中水的摩尔量为酚的1到10倍。根据本发明，在无催化剂和温和条件下可以生产高纯度的色酮化合物。此外，本发明提供了一种工业生产该化合物的手段，而不使用大量的酸或碱作为反应促进剂或催化剂，否则会引起副反应、设备腐蚀等问题。
