Description
技术领域
本发明涉及医药、有机化工及精细化工领域,特别氮杂吲哚、磷酰胺类化合物的合成方法。
背景技术
磷酰胺结构广泛存在于药物分子中,经常用来做金属有机化学反应的配体,因此磷酰胺的合成在医药、有机合成等领域中占有重要地位(参见J.Med.Chem.2012,55,4629;J.Org.Chem.1993,58,854;J.Am.Chem.Soc.2013,135,8169;Angew,Chem.,Int.Ed.2013,52,9144.)。其传统方法常常局限于使用氯化磷及胺为原料。近年来,化学工作者也发展了多种磷酰胺的合成方法。例如,铜或碘催化的亚磷酸与胺的氧化偶联(参见Org.Lett.2013,15,418;Chem.Commun.2013,49,8919;Org.Lett.2013,15,6062.)。氮杂吲哚广泛存在于天然产物生物碱及药物中,同时也是常作为有机合成的中间体(参见Cancer Res.2010,70,5518;J.Med.Chem.2013,56,7060;J.Am.Chem.Soc.2000,122,2541.)。因此近年来化学工作者对该结构的研究、化学修饰研究也比较多,如N-芳基氮杂吲哚的氰化,氯化,酰氧化、炔基化、烯基化等(参见J.Org.Chem.2016,81,6525;J.Org.Chem.2017,82,12406;Chem.Eur.J.2016,22,17926;Org.Biomol.Chem.2016,14,2944;Org.Lett.2014,16,5294.)。
