A simple and stereoselective synthesis of primary (E)-allylamines 1 and 1-azadienes 5, 7 is reported. N-Phosphorylated azadienes 5 and 7 are obtained by addition of phosphorus 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 ss-aminophosphane oxides 17, phosphonates 18, and phosphonic acid derivatives 19.

By reacting dialkyl 1-oxo- or 2-oxoalkylphosphonates with benzhydrylamine followed by reduction with triacetoxyborohydride and acid hydrolysis gave corresponding aminoalkylphosphonic acids with satisfactory yields. The use of benzylamine, α-methylbenzylamine and tritylamine was unsuccessful in the case of dialkyl 1-oxoalkylphosphonates whereas conversion of 2-oxoalkylphosphonates was also achieved although with lower yields.

The reaction of optically active α-methylbenzylamine with phosphonates containing an unsaturated carbon in the β position results in a mixture of cis- and trans-aminovinylphosphonates.Reduction with NaBH4/CH3COOH/THF produces benzylaminopropylphosphonates

The reaction of sodium alkylphosphinates or sodium dialkylphosphonates with tosylamino tosylates of amino alcohols derived from 1-aminoalkylcarboxylic acids gives high yields of optically active 2-tosylaminoalkylphosphinic or phosphonic esters.
ANIMATION REDUCTRICE DES β-CETOPHOSPHONATES: PREPARATION D'ACIDES AMINOALKYLPHOSPHONIQUES

Diethyl 2-oxo-alkylphosphonates undergo reductive amination in the presence of an amine and sodium cyanohydridoborate (NaBH3CN) in MeOH at Ph 7-7.5.Studies with a large variety of ketophosphonates show that the reaction rate is very sensitive to steric hi
