© 2014 Springer Science+Business Media New York. A reaction of triethyl phosphite with 3-alkyl-1-phenylnaphthoxazines in the presence of halotrimethylsilanes with subsequent removal of the trimethylsilyl group by hydrolysis furnished diastereomeric α-aminoalkylphosphonic derivatives of Betti base. The highest diastereomeric excess was observed in the reaction with bromotrimethylsilane at low temperature. In the case of 3-isobutyl-1-phenylnaphthoxazine, a major diastereomer was isolated from the reaction mixture by crystallization. X-ray diffraction analysis was used to establish relative configuration of its chiral centers. This method can be also used for the preparation of α-aminobenzylphosphonic derivatives, which was shown using 1,3-diphenylnaphthoxazine as an example. Major diastereomers of α-aminobenzyl- and α-aminoalkylphosphonic acid derivatives of Betti base obtained according to this procedure have different relative configurations of their chiral centers. |
