手性稠环吡喃并二氢吡咯类化合物的制备方法
技术领域
本发明属于有机合成技术领域，具体涉及一种手性稠环吡喃并二氢吡咯类化合物的制备方法。
背景技术
环加成反应是两个或多个分子的环合反应，它可以对化合物进行并环形成稠环类化合物，或者对直链化合物进行环合得到各种不同环系的化合物。近年来，过渡金属催化进行的环加成反应是化学研究的热点，尤其是铑催化的环加成反应，它以高立体选择性和转化率可以高效地合成含特定构型的化合物，这对手性药物化合物的合成具有重要的意义和应用前景。近些年，N-磺酰基-1,2,3-***的开环衍生的α-亚氨基铑卡宾配合物引起了有机化学家的关注，它能进行各种化合物，特别是含氮杂环类化合物的合成。
稠合双环缩醛和N-杂缩醛类化合物普遍存在于许多生物活性天然产物中作为关键骨架结构。这些双环缩醛的主要部分以呋喃并[2,3-b]吡喃、呋喃并[2,3-b]呋喃、吡咯并[2,3-b]吡喃及吡咯并[2,3-b]呋喃]等形式存在。其中，具有手性稠环吡喃并二氢吡咯类化合物是重要的一类衍生物。由于结构中存在多手性碳，其合成方法相当不容易，很难大范围推广应用。本发明利用稠环糖的优良手性，作为底物与N-磺酰基-1,2,3-***反应，可简单高效的合成各种手性稠环吡喃并二氢吡咯类化合物。
发明内容
本发明解决的技术问题是提供了一种简单高效的手性稠环吡喃并二氢吡咯类化合物的制备方法，该方法以Rh2(TFA)4为催化剂反应得到预期产物，并且通过糖环自身的手性可以高区域选择性的得到单一构型产物。
本发明为解决上述技术问题采用如下技术方案，手性稠环吡喃并二氢吡咯类化合物的制备方法，其特征在于具体步骤为：向装有磁子的烧瓶中加入烯糖类化合物1和催化剂Rh2(TFA)4，再加入溶剂二氯乙烷(DCE)进行溶解，于60～100℃搅拌反应，将1,2,3-三氮唑类化合物2的DCE溶液滴加到上述混合体系中，滴加完毕后继续反应0.5小时，TLC检测反应完毕后减压蒸馏除去溶剂，经硅胶柱色谱分离得到目标产物；
合成过程中的反应方程式如下：

我们以4-苯基-1-对甲苯磺酰基-1,2,3-三氮唑1a和廉价易得的3,4,6-三-O-乙酰基-D-葡萄烯糖2a为反应底物，进行了一系列条件优化。首先将反应温度改变至60℃和100℃，都没有取得令人满意的效果，最终我们将反应温度确定为80℃。同时，我们又对反应的溶剂进行了筛选，发现DCE作为反应溶剂效果最好。接下来，我们又对反应底物的比例、浓度、催化剂用量进行了优化(表1)。
综上所述，我们得到了最优反应条件即以1a：2a：Rh2(TFA)4＝2:1:0.02的投料摩尔比，反应温度为80℃，DCE为溶剂，反应0.5小时作为最优的反应条件。
