Methyl 3-alkyl-2,3-dihydro-3-furancarboxylates were prepared by the alkylation of methyl 2,3-dihydro-3-furancarboxylate using lithium diisopropylamide as the base, and alkyl halides, acetone or benzaldehyde as the alkylating agent. Likewise alkylation of methyl 2,5-dihydro-2-furancarboxylate gave the corresponding 2-alkylated products.
以二异丙基酰胺锂为碱,以烷基卤化物、丙酮或苯甲醛为烷基化剂,通过 2,3- 二氢-3-呋喃羧酸甲酯的烷基化反应,制备出 3-烷基-2,3-二氢-3-呋喃羧酸甲酯。 同样,2,5-二氢-2-呋喃甲酸甲酯的烷基化反应也得到了相应的 2-烷基化产物。
