, (2019/02/04)
The invention discloses an all-natural carbon source raspberry ketone preparation method, which comprises: carrying out a demethylation reaction on naturally-derived p-anisaldehyde as a raw material to prepare p-hydroxybenzaldehyde, carrying out a Knoevenagel condensation reaction on the p-hydroxybenzaldehyde and ethyl acetoacetate derived from biomass to obtain ethyl (E/Z)-2-acetyl-3-(4-hydroxyphenyl)acrylate, and carrying out hydrogenation, hydrolysis and decarboxylation to prepare the raspberry ketone. According to the present invention, the method can achieve the preparation of the all-natural carbon source raspberry ketone, and has advantages of simple route, easy operation, environmental friendliness, high yield and the like.
