Description
技术领域
本发明属有机合成技术领域,具体涉及高价碘催化的新型螺环化合物的制备。
背景技术
螺环骨架是十分重要的,其广泛存在于生物活性分子、药物和天然产物中。螺环化合物的传统制备方法往往需要严苛的反应条件和繁琐的合成步骤,因此发展新型高效的合成策略是非常必要的。近年来,过度金属催化的去芳构化策略被广泛研究,已经被用于各种螺环化合物的制备。但是由于过渡金属的参与,最终产物里不可避免地存在金属残留,这一点是制药企业无法接受的。因此发展无金属参与的方法用于制备螺环化合物意义重大。
发明内容
发明目的:为了克服上述现有技术的不足,作为对现有螺环化合物合成方法的补充,本发明提供了一种高价碘催化的新型螺环化合物的制备方法。
技术方案:为实现上述目的,本发明采用的技术方案为:
高价碘催化的新型螺环化合物的制备,所述新型螺环化合物具有式I所示的结构:
R1取代基选自苯基、对甲基苯基、对甲氧基苯基,R2取代基选自三氟甲基,R3取代基选自甲基;其特征在于,向反应器中,加入N-苄氧基苯甲酰胺和高价碘试剂。在溶剂中搅拌,反应结束后,使用旋转蒸发仪除去溶剂得到粗产物,粗产物经过硅胶柱层析分离得到目标化合物。其化学过程见反应式II:
所述的N-苄氧基苯甲酰胺和高价碘试剂的摩尔比值为1∶1.1。所述溶剂为二氯甲烷,反应温度为室温,反应时间为3小时。
本发明的有益效果为:本发明提供的新型螺环化合物的合成方法科学合理,提供了一种合成螺环化合物的新途径,通过本方法得到了具有多种取代基的新型螺环化合物,其特点为合成方法简单,目标产物收率较好,产品易于纯化。
