反-2-十一烯酸是一種有機(jī)中間體,有文獻(xiàn)報(bào)道其可由壬醛和膦?;宜峒柞ザ阴ヒ徊椒磻?yīng)制備得到或者由十一烷酸氧化得到。
N2氣氛下,將NaH(油中60%w / w,0.054 mol)懸浮在THF(N2氣氛)中,在5分鐘內(nèi)滴加膦?;宜峒柞ザ阴ィ?4 mmol)。在室溫下繼續(xù)攪拌約2-3分鐘。15分鐘內(nèi)滴加壬醛(49 mmol),繼續(xù)攪拌2 h,用Et2O稀釋溶液,用飽和NaHCO3水溶液和鹽水洗滌,干燥合并的有機(jī)萃取液(MgSO4)并蒸發(fā)。用15∶1己烷/ EtOAc在硅膠(5.0×20cm)上通過(guò)快速色譜純化殘余物,得到產(chǎn)物反-2-十一烯酸。
The crystal packing of trans-2-Undecenoic acid (E)-undec-2-enoic acid) is described by layers of acid dimers parallel to the (0 4 1) plane which are featured by layers of polar headgroups and hydrophobic hydrocarbon chains. The carboxylic group and the following three carbon atoms (C2, C3, C4) of the trans-2-Undecenoic acid (E)-undec-2-enoic acid) molecule lie in one plane, whereas the atoms of the hydrocarbon chain starting from C4 until C11 adopt a nearly fully staggered conformation.
