甘油与苯甲醛反应,生成1,3-亚苄基甘油及1,2-亚苄基甘油。1,3-亚苄基甘油经苄醚化反应,生成1,3-亚苄基甘油苄醚,它们是合成肾髓质抗高血压脂的重要中间体。本文研究了它们的NMR谱,依据~1HNMR数据指定了缩合反应和苄醚化反应产物中各顺式和反式异构体的构型,确认了1,3-亚苄基甘油中构象异构体的存在。本文报道了在氘代氯仿溶液中观察到的这类化合物中发生的构型和构象转变。
Glycerol reacts with benzaldehyde to produce 1,3-benzylideneglycerol and 1,2-benzylideneglycerol. 1,3-Benzylidene glycerol benzyl etherification reaction to generate 1,3-benzylidene glycerol benzyl ether, which is an important intermediate for the synthesis of anti-hypertensive medulla medulla. Their NMR spectra were studied in this paper. Based on the ~ 1H NMR data, the conformations of the cis and trans isomers in the condensation reaction and the benzylation products were confirmed. The conformational isomerism of 1,3-benzylideneglycerol The existence of the body. This paper reports the conformational and conformational changes that occur in this class of compounds observed in deuterated chloroform solutions.
