摘要
4-苄氧基苯甲醛(Ⅱ)与丙二酸二甲酯脱水缩合,产生2-甲氧羰基-3-(4-羟苯基)丙烯酸甲酯(Ⅲ),收率为88%,化合物(Ⅲ)经过催化氢化,以95%的收率得到中间体2-甲氧羰基-3-(4-羟苯基)丙酸甲酯(Ⅰ),(Ⅰ)的合成总收率达到73.6%。产品的结构经过IR、ESI-MS1、H NMR确证。
2-Methoxycarbonyl-3-(4-benzyloxyphenyl)acrylic acid methyl ester ( Ⅲ ) was obtained by condensation of 4-benzyloxybenzaldehyde ( Ⅱ) and methyl malonate with 88% yield, and catalytic hydrogenation of compound ( Ⅲ ) gave intermediate methyl 2-methoxycarbonyl-3-(4-hydroxyphenyl) propionate ( Ⅰ ) with yield of 95%. The total yield of ( Ⅰ ) was 73.6%. The structure of products were confirmed by IR, ESI-MS and ^1H NMR.
