The pyruvic acid dimethyl hydrazone can be easily prepared in ether. This compound, after deprotonation with alkyllithium, forms a strong nucleophile which on treatment with electrophiles and acidic work up yield α-ketoacids, α-hydroxybutenolides or α,γ-diketoacids.
丙酮酸二甲基肼可以在醚中容易制备。该化合物经过烷基锂去质子化后形成强核亲体,随后与电亲体反应并经过酸性处理可得到α-酮酸、α-羟基丁内酯或α,γ-二酮酸。
