    The invention concerns a method for preparing p-hydroxymandelic compounds optionally substituted and their derivatives. More particularly, it concerns a method for preparing p-hydroxymandelic acid and methoxy-3 p-hydroxymandelic acid and their derivatives. The invention concerns a method for preparing p-hydroxymandelic compounds optionally substituted and their derivatives, which consists in condensing in water, in the presence of an alkaline agent, an aromatic compound bearing at least a hydroxyl group and whereof the position in para is free, with glyoxylic acid, said method being characterised in that the reaction is carried out in the presence of an efficient amount of a compound bearing at least two carboxylic functions.
    这项发明涉及一种制备p-羟基曼德酸化合物及其衍生物的方法。更具体地说,涉及一种制备p-羟基曼德酸和甲氧基-3 p-羟基曼德酸及其衍生物的方法。这项发明涉及一种制备可选替代的p-羟基曼德酸化合物及其衍生物的方法,包括在水中,在碱性试剂的存在下,使至少带有一个羟基的芳香化合物与乙醛酸缩合,所述方法的特征在于在至少含有两个羧基功能的化合物的有效量存在下进行反应。
