Technology Process of diethylphosphonate

There total 2 articles about diethylphosphonate which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 78.0%

benzaldehyde (100-52-7) + diethyl (R)-(1-aminoethyl)phosphonate hydrochloride (98820-85-0) → diethylphosphonate (98820-80-5)

Guidance literature:

With sodium ethanolate; In ethanol; Ambient temperature;

DOI:10.1021/jm00151a005

Reference yield:

diethyl 1-aminoethylphosphonate (54788-35-1) + benzaldehyde (100-52-7) → (1-{[1-Phenyl-meth-(E)-ylidene]-amino}-ethyl)-phosphonic acid diethyl ester (64244-31-1,98820-80-5)

Guidance literature:

In benzene;

Reference yield: 87.0%

methyl methacrylate (97-63-2,9003-42-3) + (1-{[1-Phenyl-meth-(E)-ylidene]-amino}-ethyl)-phosphonic acid diethyl ester (64244-31-1,98820-80-5) → (2R,3R,5S)-5-(Diethoxy-phosphoryl)-3,5-dimethyl-2-phenyl-pyrrolidine-3-carboxylic acid ethyl ester (82240-43-5,117102-95-1)

Guidance literature:
