摘要 |
A novel process is provided for the preparation of carbofuran and certain intermediate products. 1,2-Cyclohexanedione is alkylated with a beta-methallyl compound and the resulting product subjected to a Claisen rearrangement/aromatization to provide the carbofuran phenol. Reaction of the phenol with methyl isocyanate converts the phenol to the desired carbofuran. |
