合成了衣康酸的三种甲酯:衣康酸双甲酯、衣康酸α-单甲酯和衣康酸β-单甲酯.根据它们甲酯基NMR谱中的化学位移和共轭理论,提出了衣康酸中α-羧基的酸性应大于β-羧基酸性的观点.
Three methyl esters of itaconic acid: dimethyl itaconate, α-monomethyl itaconate and β-monomethyl itaconate were synthesized according to the chemical shifts and conjugations in their methyl ester based NMR spectra Theory, it is proposed that the acidity of the α-carboxyl group of itaconic acid should be greater than that of β-carboxyl acid.
