Abstract

5-Phenylcyclophosphamides have been synthesized from benzyl cyanide via carbethoxylation, reduction, and finally condensation with bis(2-chloroethyl)-phosphoramidic dichloride. The two diastereomers have been separated and their structures have been assigned on the basis of ir, P-31 nmr and X-ray crystallography.
