Description
技术领域
本发明属于有机物合成技术领域,具体涉及含三氟甲基的螺[4,5]癸烷类化合物及其制备方法。
背景技术
含氟螺环化合物不仅是重要的有机合成砌块,而且是天然产物和活性成分的重要骨架。由于三氟甲基基团具有独特的性质,将其引入有机分子中可以显著改变分子的稳定性、亲脂性以及生物利用度等性质,因此开发出高效、可持续的向分子中引入三氟甲基基团的反应在医药、材料等领域中具有重要的研究价值。而螺[4,5]癸烷是具有三维结构的复杂环状分子,广泛存在于天然产物以及生物活性成分中。将三氟甲基基团引入螺[4,5]癸烷中,一方面会改善其理化性质,进一步增加其药性;另一方面含三氟甲基的螺[4,5]癸烷结构也是有机合成中重要的合成砌块。然而自然界中几乎不存在天然的含三氟甲基的螺[4,5]癸烷类化合物,需要通过开发有机合成方法来构筑。对于构筑含三氟甲基的全碳螺[4,5]癸烷类化合物的方法鲜有报道,因此急需开发一种高效制备含三氟甲基的螺[4,5]癸烷类化合物的方法。
铁在自然界中储量大,且对环境、人体的危害小,相对于铜更加经济、绿色,但是对于铁活化Togni’s试剂来构筑含三氟甲基的化合物的方法鲜有报道。
