Synthetic route
The commonly used synthesis methods in industry and laboratory include:
Methylation method of protocatechuic aldehyde:
Starting from 3,4-dihydroxyBenzoic aldehyde, the target product is selectively methylated with iodomethane or dimethyl sulfate under alkaline conditions.
Isoferulic acid oxidation method:
Isocoumarin was prepared by oxidative decarboxylation reaction using isoferulic acid as a precursor, which is suitable for the transformation of natural extracts.
Biological synthesis pathway:
It can be obtained through enzymatic conversion of natural components in vanilla beans and is suitable for the preparation of high-purity scientific research grade products.
