Abstract
下式芳醚制法是将硫酸3-氯-1,2-丙二醇酯与式Ar-OH的酚在无机碱存在下反应:
Description
本发明涉及下式芳醚制法:
其中Ar为必要时取代的芳基或杂环芳基。
式(Ⅰ)产品特别是可作为中间产物制取β-肾上腺素功能阻滞剂,其特点是存在3-烷基氨基-2-羟基丙氧基链,如醋丁酰心安,氨酰心安,心得宁,美多心安,噻吗心安,nadolol或Pindolol。
一般来说,β-肾上腺素功能阻滞剂可将伯胺与式(Ⅰ)环氧化物反应而得,而式(Ⅰ)化合物本身又可将表氯醇与下式酚反应而得
Ar-OH (Ⅱ)
其中Ar如前定义。但必须用过量的表氯醇来限制副产物如Ar-O-CH2-CH(OH)-CH2-O-Ar的形成。虽然采用了过量表氯醇,但副产物的形成会大大降低式(Ⅰ)产物的产量和式(Ⅰ)产物所必须的纯度或用式(Ⅰ)产物获得的产品。
现已发现并且也是本发明的目的,式(Ⅰ)芳醚可将下式硫酸3-卤代-1,2-丙二醇酯与式(Ⅱ)酚反应而得,其中产量高,而且无副产物形成:
其中X为卤原子(氯,溴),而式(Ⅱ)中Ar定义同前,其中连续经过下式产物:
其中Ar和X定义同前,而M为氢原子或碱金属原子或铵离子,这不必进行分离。
一般来说,式(Ⅲ)环状硫酸酯与式(Ⅱ)酚的缩合在水或有机溶剂或含水有机介质中于0-80℃并在选自碱金属氢氧化物(氢氧化钠),碱金属碳酸盐或重碳酸盐(碳酸钠),氨或氢氧化季铵(氢氧化四丁基铵)的碱存在下进行。
有机溶剂可用腈(乙腈),酮(丙酮),醇(乙醇),酯(乙酸乙酯),酰胺(二甲基甲酰胺)或卤代脂肪烃(二氯甲烷)。
一般来说,可采用摩尔量稍为过量,优选近于10%过量的式(Ⅲ)环状硫酸酯,以式(Ⅱ)酚计。
在采用带可与式(Ⅲ)环状硫酸酯反应的式(Ⅱ)酚时,可有利地用适当保护基进行保护,而后续无需借助其它分予残基就可除去保护基。
式(Ⅰ)产品可用常规技术从反应混合物中分出。
式(Ⅲ)的硫酸3-卤代-1,2-丙二醇酯可将相应的亚硫酸酯氧化而得。
一般来说,氧化可用次卤酸盐(碱金属或碱土金属次氯酸盐或次溴酸盐),优选次氯酸钠,次氯酸钾或次氯酸钙并在催化量的优选自钌氧化物(Ⅳ)(RuO2)和氯化钌(RuCl3)的钌衍生物存在下进行。
该法可在含水或双相含水有机介质中进行。
在该法于双相含水有机介质中进行时,溶剂一般可选自脂肪烃或环脂烃,必要时可卤代,如己烷,环己烷,乙氯甲烷,氯仿,四氯化碳或二氯乙烷,以及酯,如乙酸乙酯或乙酸甲酯。
一般来说,钌衍生物的催化量为10-6-10-1mol/环状亚硫酸酯。
式(Ⅲ)环状硫酸酯可按已知方法从反应介质中分出。
环状亚硫酸3-卤代-1,2-丙二醇酯可按已知方法,特别是按见于D.S.Breslow et H.Solnik,“The Chemistry of Heterocyclic Compounds-Multi-Sulphur and Sulphur and Oxygen 5-and 6-Membered Heterocycles”,1966,Part I,p.1 et Part Ⅱ,P.663或H.F.Van Woerden,Chem.Rev,63,557(1963)的方法制得。
含3-烷基氨基-2-羟基丙氧基的β-肾上腺素功能阻滞剂可按已知方法将伯胺与式(Ⅰ)的产品反应而制得。
该阻滞剂也可将伯胺与式(Ⅳ)产物在酸性或碱性介质中反应后用羟基代换硫酸残基(SO4H)而制得。
式(Ⅳ)产品为新产物,同时构成本发明另一目的,该产品可通过控制式(Ⅲ)环状硫酸酯与式(Ⅱ)酚的缩合反应而得。在所有环状硫酸酯均被消耗时,反应混合物酸化并分出式(Ⅳ)产物。
以下非限制性实例详述本发明。
实例
在装有搅拌器的反应器中,引入2.21g2-乙酰基-4-丁酰氨基酚(10mmol),2g硫酸3-氯-1,2-丙二醇酯(11.5mmol)和30Cm3乙腈。然后加0.5g氢氧化钠的2.5Cm3水溶液。
20℃左右搅拌5小时直至获得均匀混合物。然后50℃下加热25分钟。滤出沉淀。之后加0.9g氢氧化钠的1.5Cm3水溶液。搅拌10分钟后,滤出沉淀。减压浓缩所得溶液。可得到2.5g1-(2-乙酰基-4-丁酰氨基苯氧基)-2,3-环氧丙烷,其特性同于比较样品
产量90%左右。
硫酸3-氯-1,2-丙二醇酯制法如下:
在250Cm3园底烧杯中,引入4.96g亚硫酸3-氯-1,2-丙二醇(0.003mol)和25Cm3水。冷至0℃后加22.5Cm3次氯酸钠水溶液,其浓度为2mol/l(或0.045mol)其中含4.5mg氧化钌(Ⅳ)二水合物(0.027×10-3mol)同时进行搅拌。
然后在2℃下搅拌5分钟。2次用20Cm3二氯甲烷萃取反应混合物。有机相用0.5Cm3异丙醇处理后用15Cm3水洗涤。有机相干燥和减压浓缩(2mm汞,0.47KPa)后得3.95g无色液态硫酸3-氯-1,2-丙二醇酯。
产量为76.4%。
