The synthesis and some reactions of imines derived from aminoalkylbisphosphonates and 2-aza-1,3-butadienes is described. Bisphosphonylalkylimino compounds are useful intermediates in the preparation of aminoalkylbisphosphonate derivatives by reduction of the imino linkage with sodium triacetoxyborohydride as well as in the synthesis of 2-aza-1,3-butadienes by an olefination reaction. The electrocyclization
描述了衍生自氨基烷基双膦酸酯和2-氮杂-1,3-丁二烯的亚胺的合成和一些反应。双膦酰基烷基亚氨基化合物是有用的中间体,用于通过还原与三乙酰氧基硼氢化钠的亚氨基键来制备氨基烷基双膦酸酯衍生物,以及在通过烯烃化反应合成2-氮杂-1,3-丁二烯中。磷酸化的2-氮杂-1,3,5-三烯的电环化得到取代的2-磷酸化的吡啶。
