4.2.3.52 | geranyl diphosphate = (4S)-beta-phellandrene + diphosphate | a 1,3-hydride shift from C3 to C8 of the cyclohexene nucleus is involved in the formation of phellandrene | Pinus contorta | |
4.2.3.114 | geranyl diphosphate = gamma-terpinene + diphosphate | ionization of geranyl diphosphate folded in left-handed helical form gives, by syn-isomerization, (3R)-linalyl diphosphate, which by rotation about C2-C3 provides the cisoid, anti-endo conformation. Ionization and cyclization of this bound intermediate yield the (4R)-alpha-terpinyl cation that, following the 1,2-hydride shift, affords the terpinen-4-yl cation. Loss of the (5S)-proton terminates the reaction to generate gamma-terpinene | Thymus vulgaris | |
4.2.3.115 | geranyl diphosphate = alpha-terpinene + diphosphate | the isomerization-cyclization involves a 1,2-hydride shift in the terpinyl cation to the terpin-4-yl-cation | Dysphania ambrosioides |
