Abstract
本发明公开了一种硫亚胺酯化合物的合成方法,在室温的温和条件下,以经济易得的伯磺酰胺,醇类化合物和硫酚作为反应底物,氢氧化钙为碱,十分廉价的三氯异氰尿酸和微量的水为添加剂,三氟甲苯为溶剂。与现有技术相比较,本发明方法具有以下优点:反应体系简单且底物范围广,芳香族和脂肪族伯磺酰胺均适用于该方法,醇的适用范围广。本发明合成方法突破了现有方法的局限,具有显著的优点:底物范围广泛且可以包括多个复杂分子;反应产率较高;操作比较简单、反应条件温和、原料廉价易得。以上优点非常有利于工业放大与实际应用。
Description
技术领域
本发明涉及一种新型的硫亚胺酯化合物的合成方法,属于有机合成技术领域。
背景技术
硫亚胺酯是四价硫化合物,硫原子与碳、氮和氧原子形成共价键。硫亚胺酯是磺酰胺类药物重要的类似中间体,在具有生物活性的天然产物和配体中普遍存在,并且具有一定的杀菌和抗菌活性((a)Russ. J. Org. Chem., 1966, 2, 890; (b)Russ. J. Org. Chem., 1988, 24, 665-666; (c)Russ. J. Org. Chem., 1992, 28, 1718-1721)。硫亚胺酯的合成存在着相当大的局限性。在2020 年之前,该官能团的合成仅限于苛刻且非选择性的合成方法。例如:一种非常早期的方法涉及醇或烷氧化合物与 N-砜基硫亚胺氯的反应(Russ. J. Org. Chem., 1966, 2, 890);1987年,Kresze课题组报道了N-甲苯磺酰基-S-烯丙基亚磺酰胺与重氮甲烷的烷基化反应,得到硫亚胺酯(Phosphorus,Sulfur Silicon Relat. Elem., 1987, 29, 49-56);一个用氯胺-B 进行硫亚胺酯化的例子(Sulfur Rep.,1993, 14, 149-215);1991年和1993年,Alois课题组分别用硫亚胺氯和硫亚胺氟在甲醇中制备硫亚胺酯((a)Chemische Berichte, 2006, 125, 581-589; (b)Chemische Berichte, 2006, 126, 1529-1531);1998年,Stephen课题组用Pd(0)和三苯基膦类化合物催化还原亚磺酰亚胺酯得到硫亚胺酯(Tetrahedron Letters1998, 39, 8499-8502)。2020年之后,逐渐发展了各种催化体系合成硫亚胺酯,但原料不是商品化,需要经过多步反应预合成,而且底物范围较差。例如: 2020年,Renzo 课题组使用预合成的次磺酰胺作为S供体,使用磺酰氧基氨基甲酸酯作为N源,醇作溶剂合成硫亚胺酯(Org. Lett., 2020, 22,7129-7134);2023年,Siegfried课题组在电化学条件下用次磺酸酯与磺酰胺反应或者硫醚与磺酰胺在醇作溶剂下反应得到相应的硫亚胺酯(JACS Au,2023, 3, 575-583)。以上方法采用原料一般都是非商品化,需要繁琐的方法经过多步合成,增加了成本与环境负担,不符合绿色化学与可持续发展的要求,而且底物比较局限,一般只能合成简单取代的硫亚胺酯。导致其难以实现工业化应用。因此,发展一种底物适应范围广泛、绿色、温和、高效、环境友好的由伯磺酰胺制备硫亚胺酯的方法有十分重要的意义。
发明内容
本发明的目的是提供一种绿色高效的新型方法来合成硫亚胺酯类化合物。
为达到上述发明目的,本发明采用的技术方案是:
一种硫亚胺酯化合物的合成方法,以伯磺酰胺,醇类化合物和硫酚类化合物为原料,在碱、有机卤化试剂存在下,反应制备硫亚胺酯化合物。优选的,在室温条件下,以伯磺酰胺,醇类化合物和硫酚类化合物为原料,氢氧化钙为碱,三氯异氰尿酸和水为添加剂,三氟甲苯为溶剂,反应制备硫亚胺酯化合物。
本发明中,所述伯磺酰胺的化学结构式如下:

所述醇类化合物的化学结构式如下:

所述硫酚类化合物的化学结构式如下:

具体实施方式
本发明操作方法为本领域常规方法,以伯磺酰胺为底物、氢氧化钙为碱、有机氯化试剂和水为添加剂、有机溶剂为反应体系,无需其他物质,在室温的反应条件下,空气中即可高效得到产物硫亚胺酯化合物,为一种绿色、环保、温和、高效、节能的策略。
上述技术方案中,反应在溶剂中进行,溶剂为丙酮、N,N-二甲基甲酰胺、甲苯、乙腈、1, 2-二氯乙烷、四氢呋喃、二甲亚砜、N-甲基吡咯烷酮、叔丁醇;优选溶剂为三氟甲苯。所述温度条件为25 ℃;反应的时间为12 h。所述有机卤化试剂为次氯酸叔丁酯、1,3-二氯-5,5-二甲基海因、N-氯代琥珀酰亚胺、1,3-二溴-5,5-二甲基海因、N-溴代琥珀酰亚胺、1,3-二碘-5,5-二甲基海因、N-碘代琥珀酰亚胺、三氯异氰尿酸。
本发明采用绿色、温和、环境友好的方案制备硫亚胺酯化合物。该反应在室温的环境中就能够发生,需要的反应活化能较低;同时该反应的底物和活化剂均为廉价的商品,不需要经过多步反应合成;反应不需要在复杂的体系中进行,相对于现有的方案更加绿色温和、环境友好;该反应操作极为简便。现有的制备硫亚胺酯化合物的方法原料一般都需要预合成,步骤经济性较差,官能团普适性较差,一般只能制备简单取代的产物。与此相比,本发明具有成本低廉、绿色可持续、底物适应范围广,反应条件以及操作方法简便,产物产率较高,等显著优势,非常有利于工业生成与实际应用。
