Methods for preparation of lycopenes from C-15 Wittig salts and methods for purification of high all-E containing and high 6Z containing C15-Wittig salts

The present invention relates to methods for preparation of lycopenes, especially to lycopenes with high all-E contents or high 6Z contents from C15-Wittig salts mixtures (with high all-E-contents and high 6Z-contents, respectively). C15-Wittig salts mixtures are purified and 6Z-C15-Wittig salts are extracted from the mixtures. The extracted 6Z-C 15-Wittig salts are used in the synthesis of lycopenes with high 6Z contents and the residues are used in the synthesis of lycopenes with high all-E contents.

Synthesis, Isolation, and NMR-Spectroscopic Characterization of Fourteen (Z)-Isomers of Lycopene and of Some Acetylenic Didehydro- and Tetradehydrolycopenes

Eight (Z)-isomers of lycopene were prepared by stereocontrolled syntheses and fully characterized by 1H-NMR, 13C-NMR, mass, and UV/VIS-spectroscopy: (5Z)-, (7Z)-, (15Z)-, (5Z,5'Z)-, (7Z,7'Z)-, (7Z,9Z)-, (9Z,9'Z)-, and (7Z,9Z,7'Z,9'Z)-lycopene.Six additional (Z)-isomers, namely (9Z)-, (13Z)-, (5Z,9'Z)-, (9Z,13'Z)-, (5Z,9Z,5'Z)-, and (5Z,13Z,5'Z)-lycopene, were isolated in small quantities from isomer mixtures by semiprep.HPLC and were identified by 1H-NMR spectroscopy.
