chlorides 3 to unsaturated oximes 2, while azadienes 24 are prepared by olefination reactions of functionalized enamines 20/21. Reduction of azadienes 5, 7, 24 and derivatives 13/14 and 20/21 with hydrides, followed by deprotection of the resulting amines leads to the formation of primary allylamines 1 and β-aminophosphane oxides 17, phosphonates 18, and phosphonic acid derivatives 19.
报道了伯 (E)-烯丙胺 1 和 1-氮杂二烯 5、7 的简单立体选择性合成。N-磷酸化氮杂二烯 5 和 7 是通过将氯化磷 3 添加到不饱和肟 2 中获得的,而氮杂二烯 24 是通过官能化烯胺 20/21 的烯化反应制备的。用氢化物还原氮杂二烯 5、7、24 和衍生物 13/14 和 20/21,然后对所得胺进行脱保护,形成伯烯丙胺 1 和 β-氨基膦氧化物 17、膦酸酯 18 和膦酸衍生物 19 .
