Popis:	Syntheses of α-Aminophosphonic Acids from N-Ethoxyiminium Salts, II Nitrones 2 obtained from aldehydes 1 are used for the synthesis of N-ethoxyiminium salts 3. These react with several esters of hydrogen phosphite 4 to give the N-methyl α-amino phosphonic esters 5 to 13. The N-benzyl α-amino phosphonic esters 24 and 25 can be obtained by the same procedure. Hydrogenolysis and ester hydrolysis afford the α-amino phosphonic acids 14 as well as 26 and 27, respectively.
