amino]methyl}phosphonates. -Ring opening of epoxides (II) with (aminomethyl)phosphonates (I) occurs at the sterically less hindered position on the epoxide to afford the title compounds (III) in moderate to good yields. The ring opening reaction of styrene oxide (IV) with (Ia) takes place at both positions, the sterically less and more hindered ones. The major advantages of this procedure are the simple method, easy work-up, and the solvent-and catalyst-free reaction conditions. -(KABOUDIN*, B.; SORBIUN, M.; Heteroat. Chem. 21 (2010) 5, 284-289,
