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.
