polyhydroxychalcones. Although possessing certain limitations, the most generally suitable methods involve the condensation of a suitably substituted acetophenone and the appropriate benzaldehyde by means of alkali. Most of the compounds describejd here were prepared by this general procedure. The use of Russell’s2 method was found necessary in a few cases. The preparation of certain chalcones containing the 2’-hydroxy-
许多聚羟基查耳酮和β-黄烷酮已被制备用于黄烷酮的某些还原产物的光谱研究。本研究中制备的大多数化合物都不是新的,仅在似乎需要对其性质进行一些修改的情况下才会提及。描述了八个新的查耳酮和十个新的黄烷酮,以及所有这些的酰基衍生物。Cha1cones.-fi 有相当多的方法可用于制备多羟基查耳酮。尽管具有某些限制,但最普遍适用的方法包括通过碱将适当取代的苯乙酮和适当的苯甲醛缩合。此处描述的大多数化合物是通过该通用程序制备的。在少数情况下发现有必要使用 Russell's2 方法。某些含有 2'-羟基-的查耳酮的制备
