Malania oleifera Chum is a unique renewable plant resource in China, its fruit oil has a high content of 15-tetracosenic acid, and it is a good raw material for the synthesis of cyclopentadecanone and cyclopentadecanolide. A Novel synthesis method of cyclopentadecanone and cyclopentadecanolide from vegetable oil was designed, and the synthesis yields of c cyclopentadecanone and cyclopentadecanolide were 38.5% and 63.0%, respectively. The effect of different ester groups on cyclization of α,ω-difatty acid alkyl ester in cyclopentadecanone synthesis, and effect of catalysts on cyclization ofω-hydroxycarboxylic acid triglyceride in cyclopentadecanolide synthesis were investigated. The designed synthesis strategy has the characteristics of less synthesis steps and high utilization efficiency of 15-tetracosenic acid, which has simple and economic.
蒜头果是中国特有的可再生植物资源，其果油中15-二十四碳烯酸含量较高，是合成环十五酮和环十五内酯的良好原料。设计了一种从植物油合成环十五酮和环十五内酯的新方法，环十五酮和环十五内酯的合成产率分别为38.5%和63.0%。研究了不同酯基对环十五酮合成中α,ω-二脂肪酸烷基酯环化的影响，以及催化剂对环十五内酯合成中ω-羟基羧酸甘油三酯环化的影响。所设计的合成策略具有合成步骤少、15-二十四碳烯酸利用效率高的特点，具有简便经济性。
