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
