The structures of several derivatives of bisnorquassin (2a) are clarified. Chemical support for the mechanism of formation of this novel demethylation product of quassin (1a) is provided, which together with the recent X-ray diffraction study of bisnorquassin m-bromobenzoate (2d) offers an independent corroboration of the structure and stereochemistry of 1a deduced by Valenta.

The reaction of 8 -trimethylsiloxyquinoline, 2 with PCl3, PhPCl2, and PhPF2 has furnished the corresponding 8 -quinolyl halophosphite derivatives, 3-5 . The synthesis of two metal complexes, 8 and 9, of 4 with Au(I) and Pt(II) is described. The new compounds were characterized by elemental analysis and by 1H and 31P NMR spectroscopy. A single crystal X-ray diffraction study of 4 has been conducted; a short intramolecular P ··· N contact (230.9 pm) and a long P-Cl bond (218.7 pm) were observed.
