Isotope sensitive branching and kinetic isotope effects to analyse multiproduct terpenoid synthases from Zea mays

Multiproduct terpene synthases TPS4-B73 and TPS5-Delprim from Zea mays exhibit isotopically sensitive branching in the formation of mono- and sesquiterpene volatiles. The impact of the kinetic isotope effects and the stabilization of the reactive intermediates by hyperconjugation along with the shift of products from alkenes to alcohols are discussed.

Kinetics of thermal rearrangements in the Δ2-thujene system: A full quadrisection of a perturbed bicyclo[3.1.0]hex-2-ene

Further insight into the behavior of suppositional diradicals in a caldera is sought in the thermal rearrangements among the four "Δ 2-thujenes", two 1-isopropyl-4-methylbicyclo[3.1.0]hex-2-enes [(-)-cis-1 and (+)-trans-2] and two isomers, exo- and endo-3-isopropyl-6- methylbicyclo[3.1.0]hex-2-ene [(+)-exo-3 and (-)-endo-4]. Optically pure trans-3-isopropyl-5-vinylcyclopentene (5) is the final, strongly thermochemically favored product, the result of an intramolecular homodienyl shift of a methyl hydrogen atom in (-)-endo-4. The set of twelve specific rate constants, four sets of three each, that define the interrelations among the four isomers has been extracted from data acquired starting from each isomer. An attractive mechanistic hypothesis involving an, intermediate diradical of iso conformation, common, for example, to both (-)-cis-1 and (+)-exo-3 (as educts), that proceeds to an anticonformer common to both (+)-trans-2 and (-)-endo-4 does not lead to a satisfactory rationalization of the product distribution. Addition of a second mechanistic conceptual scheme, that of a diradical-in-transit behaving as if there were a measure of continuous bonding (for example, (+)-trans-2 proceeding directly to (-)-cis-1), improves agreement with experiment. Over a 30 °C range of temperature, there is no credible change in product distribution.

CIDNP study and ab-initio calculations of rigid vinylcyclopropane systems: Evidence for delocalized 'ring-closed' radical cations

The radical cations of three terpenes, sabinene, 1, and α-, 2, and β-thujene, 3, containing vinylcyclopropane functions held rigidly in either an anti- or syn-orientation, have been elucidated by CIDNP studies. The structures assigned to these species are discussed in view of their reactivities and compared with three simplified radical cations, 2-methylenebicyclo[3.1.0]hexane, 4, bicyclo[3.1.0]hex-2-ene, 5, and 5-methylbicyclo[3.1.0]hex-2-ene, 6, calculated by ab initio molecular orbital methods.

A convenient synthesis of trans-sabinene hydrate from (-)-3-thujol via a highly selective ene reaction of singlet oxygen

trans-Sabinene hydrate (1), was synthesized from (-)-3-thujol (2) in four steps. The key step was the selective formation of trans-2-hydroxy-3-thujene (6) by photooxygenation of a 3:1 mixture of 2- and 3-thujenes (4 and 5) obtained from (-)-3-thujol mesylate (3). Hydrogenation of 6 gave compound 1 in 46% overall yield.
