| 摘 要： | 本文报道二氢茉莉酮酸甲酯的简便合成方法。先由丁二酸和庚酰氯反应得到2-戊基-1,3-环戊二酮(1),再用甲醇醚化1,可得到2-戊基-3-甲氧基-环戊-2-烯酮(2)。2与丙二酸二甲酯反应生成(2-戊基-3-酮-1-环戊烯-)基乙酸甲酮(3)。最后,催化氢化3,便可得到二氢茉莉酮酸甲酯(4)。

| Abstract: | A convenient method for the synthesis of methyl dihydrojasmonate con-sists of four steps.First,2-pentyl-1,3-cyclopentanedione(1)is obtained from reactionof succinic acid and heptanoyl chloride.Then 1 is etherized with methanol to get 2-pen-tyl-3-methoxy-2-cyclopentenone(2),which reacts with dimethyl malonate to formmethyl(2-pentyl-3-keto-1-cyclopentenyl-)acetate(3).Finally,methyl dihydrojasmo-nate(4)is obtained by catalytic hydrogenation of 3. |
