✦ Synopsis

A series of four diethyl { (3-hydroxypropyl)aminomethyl}phosphonates have been prepared and characterized. In one case, the phosphonate was transformed to a seven-membered 1,4,2oxazaphosphepane heterocycle through a one-pot intramolecular esterification. The analogous reaction with formaldehyde gave the six-membered diethyl (1,3-oxazinan-3-ylmethyl)phosphonate, which could be transformed in a posterior reaction to the corresponding aminomethanephosphonic acid.
