An efficient method for the synthesis of C-phosphonoketenimines through palladium-catalyzed migratory insertion of isocyanides has been developed for the first time. This procedure tolerates wide functional groups and has a good atom economy. Further transformations of the products, which are useful building blocks for the β-aminophosphonates, β-aminovinylphosphonates, and C-phosphorylated tetrazoles
首次开发了通过钯催化的异氰酸酯迁移插入合成C-膦烯酮的有效方法。该程序可耐受广泛的官能团,并具有良好的原子经济性。产物的进一步转化是潜在的合成用途,所述产物是β-氨基膦酸酯,β-氨基乙烯基膦酸酯和C-磷酸化的四唑的有用的结构单元。
