| titleOfInvention | Method for producing carotenoid |
| abstract | The present invention relates to a method for producing carotenoids. This process involves the preparation of a dialkoxydialdehyde of the general formula I [wherein R 1 = C 1 -C 6 -alkyl] by double Wittig condensation with a phosphonium salt of the formula II or in the formula III Reacting with the phosphonate represented by a double Wittig-Horner condensation wherein the substituents of the formulas II and III are defined independently of each other as follows: R 2 = IV; R 3 represents aryl; R 4 to R 6 represent C 1 to C 6 -alkyl, and X − represents an anion equivalent of an inorganic acid or an organic acid]. |
