| Reactant | 3,4-Dimethyl-2-methylenevaleraldehyde | HCID 3020423 | — |
| Product | 1-(1,2-Dimethyl-propyl)-4-methyl-cyclohex-3-enecarbaldehyde | HCID 89705176 | 49% |
Reaction Steps
3,4-Dimethyl-2-methylene-pentanal (550 g, obtained as detailed above) and 393 g of isoprene were charged to a Parr Bomb, heated to 160° C., and aged for 12 hours. The rushed over material provided ˜32% recovery of 1-(1,2-dimethyl-propyl)-4-methyl-cyclohex-3-enecarbaldehyde (415 g).
