摘要
以3,5-二甲氧基苄溴和对硝基苯甲醛为原料,经Witting-Hornor反应、还原、重氮化、水解得到目标物,以53·9%的总产率合成了天然多功能抗氧化剂紫檀芪,并对目标物的结构采用IR、1H NMR和EI-MS进行了表征。此合成工艺简单,操作方便,生产成本低,具有较好的工业应用前景。
Natrral multifunction antioxidant Pterostilbene was synthesized in a higher yield from 1 - Bromomethyl - 3, 5 -dimethoxy - benzene and 4 - Nitro - benzaldehyde through Witting - Hornor, hydrogenation, reduction, diazotization and hydrolization, the total yield is 53.9%. The product was confirmed by IR,^1H NMR,^13C NMR and EI - MS. The production technology was simple and operation was easy, and its cost was low, so it can be considered of good prospect for industrial application.
