2-Ethyl, 2-isopropyl and 2-benzyl-1, 3-cyclopentanediones were synthesized by the known method. Diethyl 2-methyl-3-oxoadipate was cyclized to 2-methyl-1, 3-cyclopentanedione by heating with potassium tert-butoxide. 3-Methyl-1, 2, 4-cyclopentanetrione was reduced to 2-methyl-1, 3-cyclopentanedione by Clemmensen method.
用已知的方法合成了 2-乙基、2-异丙基和 2-苄基-1,3-环戊二酮。2- 甲基-3-氧代己二酸二乙酯在叔丁醇钾的加热下环化成 2-甲基-1,3-环戊二酮。用克莱门森法将 3-甲基-1,2,4-环戊四酮还原成 2-甲基-1,3-环戊二酮。
