Methyl 4-oxoalkanoates have been obtained in good yields by treatment of 1, 2-dichloro-2-alken-4-ones with sodium carbonate in methanol followed by acid-catalyzed hydrolysis of the intermediate 5-alkyl-2,2-dimethoxy-2, 3-dihydrofurans.
在甲醇中用碳酸钠处理 1,2-二氯-2-烯-4-酮,然后在酸催化下水解中间体 5-烷基-2,2-二甲氧基-2,3-二氢呋喃,可以获得收率很高的 4-氧代烷酸甲酯。
