Method for preparing beta-Apo-8'-carotenal
2016
The invention discloses a method for preparing beta-Apo-8'-carotenal. The method includes steps of (1) synthesizing raw materials 2, 6, 6-trimethyl-1- cyclohexanemethanol and triphenylphosphine as raw materials into 2, 6, 6-trimethyl-1-cyclohexene methyl triphenylphosphine salt; (2) subjecting 2, 6, 6-trimethyl-1-cyclohexene methyl triphenylphosphine salt and 2, 6, 11, 15-tetramethyl-2, 4, 6, 8, 10, 12, 14-hexadecanoyl heptaene dialdehyde to wittig reaction to obtain beta-Apo-8'-carotenal. The method using 2, 6, 6-trimethyl-1- cyclohexanemethanol as raw materials is safe in reaction and is a novel method.
