A general and efficient access to aryl, heteroaryl, vinyl and alkynyl difluoromethylphosphonates is described. The developed methodology using TMSCF2PO(OEt)2, iodonium salts and a copper salt provided a straightforward manifold to reach these highly relevant products. The reaction proved to be highly functional group tolerant and proceeded under mild conditions, giving the corresponding products in
描述了一般和有效地获得芳基,杂芳基,乙烯基和炔基二氟甲基膦酸酯的方法。使用TMSCF 2 PO(OEt)2,碘鎓盐和铜盐开发的方法为获得这些高度相关的产品提供了直接途径。该反应被证明是高度官能团耐受的,并且在温和的条件下进行,从而给出相应的产物,收率良好至优异。该方法代表了这一重要类别的氟化支架的第一个通用合成路线,众所周知,该支架为体内稳定的磷酸盐替代物。
