α-Substituted (2-iminoalkyl)phosphane oxides were obtained from the azaenolates of imines or enamines and alkyl halides. The functionalized imines or enamines thus obtained were used for the synthesis of δ-amino esters, δ-amino phosphonates and heterocycles such as 3,4-dihydropyridin-2-ones, 2-pyridones and pyrroles containing a phosphinyl substituent.
α-取代的(2-亚氨基烷基)氧化膦从亚胺或烯胺和烷基卤化物的氮杂烯醇化物中获得。由此获得的官能化亚胺或烯胺用于合成 δ-氨基酯、δ-氨基膦酸酯和杂环,例如含有膦基取代基的 3,4-二氢吡啶-2-酮、2-吡啶酮和吡咯。
