| 4.2.3.107 | (3R)-linalyl diphosphate | - |
Pinus contorta | ? + diphosphate | the velocity of the reaction with the (3S)-linalyl enantiomer is 25fold greater than the velocity with the (3R)-enantiomer and twice that of the natural substrate, geranyl diphosphate. Cyclization of the linalyl intermediate is faster than the coupled isomerization and cyclization of the geranyl substrate | ? | |

| 4.2.3.107 | geranyl diphosphate | the H located at C1 in the geranyl substrate resides at C5 of product (+)-car-3-ene. The 5-proR hydrogen is eliminated during cyclopropyl ring closure. Cyclopropyl ring formation occurs via a (4S)-alpha-terpinyl cation derived from the anti-endo-cyclization of a (3S)-linalyl diphosphate intermediate | Pinus contorta | (+)-car-3-ene + diphosphate | - |
