Carbonyls, metal high trans effect

N.M.R. Spectroscopy. The effects of lanthanoid shift reagents on the H and C n.m.r. spectra of canthaxanthin (90) have been studied in detail. Chemical shifts and signal broadening showed that the metal binds the carbonyl group at two sites. A computer programme was used to study the conformation of canthaxanthin. Similar studies" have been performed with a -trans-, 9-cis-, 11-CW-, and 13-c/s-retinal and 8 -apo-/3-caroten-8 -al (165), A high-resolution... [Pg.238]
