Reactions of 3-hydroxyalkan-2-ones with (hetero)aromatic aldehydes under basic conditions lead to 4-aryl-1,7-dihydroxyalkane-2,6-diones. These products were also synthesized by dismutation of 4-aryl-1-hydroxyalk-3-ene-2-ones. The reactions proceed as tandem retro aldol reactions and the Michael addition.
3-羟基烷-2-酮与(杂)芳香醛在碱性条件下反应生成4-芳基-1,7-二羟基烷-2,6-二酮。这些产品也是通过 4-aryl-1-hydroxyalk-3-ene-2-ones 的歧化合成的。反应以串联逆羟醛反应和迈克尔加成的形式进行。
