A number of chalcones with the (+)- and (−)-usnic acid moieties were synthesized by the following sequence: the reaction of these acids with phenylhydrazine, reduction of the C(1)=O group with sodium borohydride, O-methylation of the intermediate compounds with diazomethane, and subsequent condensation with substituted benzaldehydes at the acetyl group.
通过以下步骤合成了许多带有(+)-和(-)-乌斯尼酸部分的查尔酮:这些酸与苯肼反应,羰基(1)=O基团与硼氢化钠还原,中间化合物与重氮甲烷进行O-甲基化,随后与乙酰基上的取代苯甲醛缩合。
