A series of 2-Z-3-phenyl-1,3,2-oxazaphosphorinanes 7-14 (Z = MeO, (CF3)2CHO, Ph, MeNH, and Me2N) containing three-coordinate phosphorus was prepared.The conformations of the six-membered rings were investigated by 1H and 31P NMR spectroscopy and X-ray cry
Conformations of Saturated Six-Membered Ring Phosphorus Heterocycles. cis- and trans-2-Oxo- and 2-Thio-2-(dimethylamino)-5-tert-butyl-1,3,2λ5-oxazaphosphorinanes: Molecules Related to Cyclophosphamide

Several 5-tert-butyl-2-(dimethylamino)-1,3,2-oxazaphosphorinanes have been prepared.Included are the NH (3 and 4) and NPh (5 and 6) oxides and sulfides.The individual diastereomers of 3-6 were separated and the cis and trans geometries determined for 4 an
