A novel process is provided for the preparation of carbofuran. 1,2-Cyclohexanedione is alkylated with a beta-methallyl compound and the resulting product subjected to a Claiserr rearrangement/aromatization to provide the carbofuran phenol. Reaction of the phenol with methyl isocyanate converts the phenol to the desired carbofuran. The intermediate, 2-β-methallyloxy-2-cyclohexen-1-one, is considered to be novel. |
