Process for producing hinokitiol |
| abstract |
A process for producing hinokitiol which comprises the step of obtaining 1-isopropylcyclopentadiene from cyclopentadiene and an isopropylating agent represented by the general formula R—X wherein R is an isopropyl group and X is a halogen or the like (first step), reacting it with a dihaloketene to obtain a ketene adduct (second step), and decomposing the ketene adduct (third step), said first step comprising the following three steps: n a) a preparation step of cyclopentadienyl metal; n b) a step of obtaining isopropylcyclopentadiene by isopropylating the cyclopentadienyl metal in an aprotic polar solvent; and n c) a step of isomerizing 5-isopropylcyclopentadiene in the product selectively to 1-isopropylcyclopentadiene with heat. |
