Dihydro-4,4-dimethyl-2,3-furandione (4e) was synthesized from diethyl oxalate, methylpropanal (1a) and formaldehyde in the presence of sodium methoxide. In a similar manner, analogs of dihydro-2,3-furandione 4 were prepared using other aldehydes.
二氢-4,4-二甲基-2,3-呋喃二酮(4e)是由草酸二乙酯、甲基丙醛(1a)和甲醛在甲醇钠的存在下合成的。类似地,使用其他醛也制备了二氢-2,3-呋喃二酮4的类似物。
