A concise ex chiral pool approach to novel bidentate camphane phosphane ligands

, p. 4118 - 4124 (2007/10/03)
The bidentate hydroxy phosphane 20 and the phosphane phosphinite 21, each bearing a camphane skeleton, were prepared in five and six steps (52% and 28% yield), respectively, from (1S)-(+)-camphorsulfonic acid 8 via the triethylsilyl-protected iodide 17 as a key intermediate. An X-ray crystal structure was obtained for 21.

Photolysis of blue, solid (+)-10-bromo-2-chloro-2-nitrosocamphane (1) with red light produces two nitroxide radicals (2) and (3), 10-bromocamphor (4), a 10-bromo-2-chloro-2-nitrocamphane (5), a 2-chloro-5,5-dimethyl-1,2-dinitrobicyclooctane (6a), and a corresponding 1-nitrato-analogue (6b).E.p.r. spectra of (2) and (3) are described and interpreted.Analyses of the 1H n.m.r. spectra of compounds (1) and (5) show that n.m.r. method can be used to determine configurations at active XCCl (X = NO or NO2) centres of gem-chloronitroso and gem-chloronitro derivatives of the terpenes.The combination of chemical and spectroscopic evidence enables some of the steps involved in the solid-state red photolysis reaction of (1) to be unravelled.
