| 摘 要： | 以歧化松香为原料,将其纯化得到脱氢松香酸,用硫酸二甲酯酯化后,通过12位溴代、7位氧化、13位硝化得到7-羰基-12-溴-13-硝基脱氢松香酸甲酯(Ⅴ),Ⅴ经过与叠氮化钠反应后,在甲苯中回流关环得到7-羰基-12,13-氧化呋咱脱氢松香酸甲酯(Ⅶ),Ⅶ再用三苯基膦脱氧得到7-羰基-12,13-呋咱脱氢松香酸甲酯Ⅷ,这两种产物的产率分别为83%和76%;产物经IR、1HNMR1、3CNMR和MS进行了表征。

| Abstract: | Disproportionated rosin was purified to get dehydroabietic acid,which by esterification with (Me)_2SO_4 gave methyl dehydroabietate(Ⅱ).Then Ⅱ was bromated at 12-position,oxidated at 7-position and nitrated at 13-position to give methyl 7-carbonyl-12-bromo-13-nitrodehydroabietate (Ⅴ).After treating Ⅴ with sodium azide,methyl 7-carbonyl-12,13-oxifurazandehydroabietate (Ⅶ) was obtained by refluxing in toluene.Ⅶ was further converted to methyl 7-carbonyl-12,13-furazandehydroabietate(Ⅷ) through reacting with triphenyl phosphine.The compounds were characterized by IR,~1HNMR,~(13)CNMR and MS. |
