An Efficient Synthesis ofN-Phosphorylated Azadienes, Primary (E)-Allylamines, and β-Amino-Phosphane Oxides and -Phosphonates from β-Functionalized Oxime Derivatives
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 phosphonicacidderivatives 19.
