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 |

4.2.3.114 | geranyl diphosphate = gamma-terpinene + diphosphate |
major products sabinene and gamma-terpinene are formed by a cyclization mechanism involving a 1,2-hydride shift in the alpha-terpinyl cation intermediate |

4.2.3.114 | geranyl diphosphate = gamma-terpinene + diphosphate |
mechanism involves the cyclizazion of the acyclic precursor, loss of a proton from C5 to form the delta4 double bond, and a 1,2-hydride shift fom C4 to C8 to give gamma-terpinene |
