| titleOfInvention | Production of terpenes |
| abstract | Terpenes into which a trans-type vinyl group (for example, an isoprene unit) has been introduced are synthesized by an aza-Claisen reaction that proceeds at a much lower temperature than before. A quaternary ammonium salt having a quaternary ammonium group on the carbon atom bonded to the vinyl group is synthesized. When a base is allowed to act on this, nitrogen ylide is produced as an intermediate. This rearrangement produces a trans-type vinyl group and at the same time an iminium salt. Thereafter, the iminium salt is reduced to obtain an amine. This reaction adds a trans-type vinyl group. This reaction proceeds at low temperatures. By repeating these reactions, useful terpenes can be synthesized. |
