化学性质
无色透明结晶,熔点为81~83℃。
用途
作为萘普生的中间体。
生产方法
通过使用β-萘酚与甲醇-硫酸进行醚化反应,生成β-甲氧基萘;随后与丙酰氯缩合得到2-丙酰基-6-甲氧基萘。最后,利用吡啶氢溴酸盐和过溴化物对其进行溴化处理,从而制得所需产品。

2-Aryl-3-alkyl-5-methyl-2-morpholinols were synthesized from the reactions of chiral 2-aminopropan-1-ol with 2-bromo-1-phenylpropan-1-one, 2-bromo-1-(3-chlorophenyl)propan-1-one, 1-(4-(benzyloxy)phenyl)-2-bromopropan-1-one, 2-bromo-1-(6-methoxy- naphthalen-2-yl)propan-1-one, and 1-(4-(benzyloxy)phenyl)pentan-1-one in N-methyl-2-pyrrolidone (NMP), respectively. The 2-aryl-3-alkyl-5-methyl-2-morpholinols were reacted with hydrogen chloride to give the hydrochloride salts with yields of 56%–77%. The structures of the products were proven by means of their 1H NMR, IR, and MS spectroscopic data. The stereochemical properties of representative products were established unambiguously by the X-ray single crystal analysis. The antidepressant activities of the title compounds were assayed by the mouse forced swimming test (FST). The FST results confirm the antidepressant properties of our products.Key words: morpholinol hydrochloride, hemiacetal, chiral synthesis, X-ray diffraction, absolute configuration, antidepressant activity.
