Paragraph 0050-0052; 0055-0057, (2021/10/27)
The invention relates to the technical field of organic synthesis, in particular to a method for preparing anethoxyl propionaldehyde by anisole, which comprises anisole and 2 - methylallyl diacetate or anisole. 2 - Methacrolein and acetic anhydride were added to the reaction vessel to catalyze the reaction. Then 1 - acetoxy -2 - methyl -3 - (4 - methoxyphenyl) propylene was added to a reaction vessel carrying an alcoholic solvent and an ester exchange catalyst to carry out an ester exchange reaction. The method solves the problems that the cost of anisic aldehyde or anisaldehyde in the product is high due to the expensive price of anisaldehyde or anethol in the prior art, and anisole is synthesized into anethol propionaldehyde. The synthetic anisanylpropanal has a sufficiently high purity. Can be used for perfumery.
