| Reactant | Propionic Acid | HCID 1032 | — |
| Reactant | 3,7,11-Trimethyldodeca-6,10-dien-1-yn-3-ol | HCID 5365823 | — |
| Reactant | Ethyl ortho-acetate | HCID 86598186 | — |
| Product | Ethyl 5,9,13-trimethyl-3,4,8,12-pentadecatetraenoate | HCID 53828293 | 96% |
Reaction Steps
In the same manner as in the preceeding Examples, 32.4 g of ethyl ortho-acetate, 22 g of dehydronerolidol and 1.5 g of propionic acid were reacted at 135 to 140°C. for 6 hours and the resulting reaction mixture was subjected to distillation under reduced pressure. Ethyl 5,9,13-trimethyl-3,4,8,12-pentadecatetraenoate was obtained in a yield of 96% from a fraction boiling at 144 to 146°C. under 0.025 mm Hg.
