✦ Synopsis

The configurational stability of the trivalent phosphorus atom is sufficient to permit optically active derivatives to exist (1-J). It follows that suitably substituted cyclic compounds with trivalent phosphorus should exist in cis and trans -isomeric forms.

Qoldwhite (4) has presented evidence from the NMH spectra of substituted 1,3,2-dioxaphospholanes that this may be the case; both the 2-chloro-Q-methyl-and the 2-methoxyh-methyl-derivatives showed the presence of two kinds of C-methyl groups. This effect also was noted for the 2-chlpro-4,4,5,5tetramethyl derivative.

However, the only case of separation

We have found that "C nmr spectroscopy is a powerful tool for the determination of the structures of &, trans isomers in the phosphorinane family. It is more definitive than 'H nmr spectroscopy; the carbon signals are well separated and have several unique features pointing to the structure, whereas

In the title compound, C~25~H~23~N~3~O~3~, molecules are linked into chains along the __c__ axis by intermolecular Cβ€”H...O hydrogen bonds. The packing is further stabilized by Cβ€”H...Ο€ and π–π interactions.
