  Reaction of N-Vinylic Phosphazenes Derived from β-Amino Acids with Aldehydes. Azadiene-Mediated Synthesis of Dihydropyridines, Pyridines, and Polycyclic Nitrogen Derivatives

  摘要：

  Enamino phosphonium salts 2 are obtained by 1,2-addition of hydrogen chloride to N-vinylic phosphazenes 1 derived from triphenylphosphine. Aza-Wittig reaction of phosphazenes 1 derived from triphenylphosphine and 6 derived from diphenylmethylphosphine with aldehydes 3 leads to the formation of 2-azadienes 7. Reaction of azadienes 7 with enamines affords dihydropyridines 9 and 11, pyridines 12, and bicyclic nitrogen heterocycles 15-18 in a regioselective fashion, while heterodiene 20 reacts in the same way with pyrrolidinocyclohexanone giving 1-azaphenanthrene compound 21. Reaction of enamino phosphonium salts 2 with aldehydes 3 gives symmetrical dihydropyridines 5.

  摘要：

  据报道，（乙烯基亚氨基）磷杂环戊烷与醛的新反应涉及乙烯基侧链的β-碳原子在羰基碳原子上的初始亲核攻击。衍生自β-叠氮丙烯酸乙酯的亚氨基磷烷4与取代的肉桂醛反应生成2-芳基吡啶和4-苯乙烯基二氢吡啶衍生物的混合物，而与取代的苯甲醛的反应提供4-芳基二氢吡啶衍生物。然而，衍生自叠氮富马酸二乙酯的亚氨基磷烷16通过预期的氮杂-维蒂希方式与肉桂醛反应，在所得二氢吡啶脱氢后得到4-芳基吡啶衍生物。

  Reaction of N-vinylic phosphazenes with α,β-unsaturated ketones leads to the formation of pyridines derived from β-amino acids in a regioselective fashion. The use of functionalized enones derived from α-acylstyryl-carboxylates or -phosphonates affords biologically active asymmetrical and symmetrical dihydropyridines substituted with carboxylate or phosphonate groups including nitrendipine, felodipine

  New reactions of (vinylimino)phosphoranes with aldehydes involving an initial nucleophilic attack of the beta-carbon atom of the vinyl side chain on the carbonyl carbon atom are reported. Iminophosphorane 4 derived from ethyl beta-azidoacrylate reacts with substituted cinnamyl aldehydes to give a mixture of 2-arylpyridine and 4-styryldihydropyridine derivatives, whereas the reaction with substituted
