本发明属于有机化合物合成及应用技术领域,涉及一种三(五氟苯基)硼烷催化的氧硫叶立德与苯乙酸、苯甲酸等羧酸进行的O-H键插入反应,同时构建C-O键,从而构建α-酰氧基酯类化合物的绿色合成方法。
背景技术
α-酰氧基酯是一类重要的双酯类化合物,具有多种生物用途。α−酰氧基酯是多种药物的活性部分,如具有镇痛作用的氟比洛芬酯[1]、具有抗菌作用的头孢呋辛酯[2]、具有抗癌活性的Cryptophycin[3]等。其合成最早是由Wolfrom等人[4]将重氮化合物引入到羧酸中,通过卡宾插入反应合成α-酰氧基酯类化合物。在工业上,重氮化合物由于其放热分解、不稳定性、对环境易造成毒性伤害以及潜在的爆炸行为而经常被避免使用。使用氧硫叶立德作为卡宾前体替代重氮化合物在一定程度上解决了这些问题,氧硫叶立德是稳定的结晶固体,在反应中产生DMSO而不像重氮化合物产生氮气,因此不会造成反应体系的压力剧烈升高,同时氧硫叶立德更持续、稳定的反应特性也可以让反应更为安全可控,且氧硫叶立德比相应的重氮化合物更亲碳核活性[5]。氧硫叶立德在这些特性被发现后,已经成功开发了其在过渡金属催化下在N-H键[6]、B-H键[7]、O-H键[8]、P-H键[9]插入反应的初步应用。有文章[8]报道氧硫叶立德与苯甲酸在金属催化剂钒的催化下可以生成α-酰氧基酯化合物。由于金属催化剂昂贵且易对环境造成污染,需要寻求绿色的非金属催化剂。在过去的几年里,三芳基硼烷在许多情况下可以取代金属催化剂用于催化有机反应。三(五氟苯基)硼烷是一种强Lewis酸,具有化学性质稳定、酸性强、使用方便等优点。B(C6F5)3已被报道可以与活性重氮化合物,生成卡宾中间体或其共振中间体,然后进行插入和亲核或者亲电取代反应[10]。
发明内容
