Synthesis of a caryophyllene isoprenologue, a potential diterpene natural product

(-)-β-Caryophyllene has been converted into three stereoisomers of a new bicyclic compound that is structurally related to the known macrocyclic diterpene, flexibilene, in the same way β-caryophyllene is related to humulene. Key steps are selective cleava

Synthesis of fluorine analogs of vitamin E. III. Synthesis of 2-[4,8-dimethyl-12-(trifluoromethyl)tridecyl]-2,5,7,8-tetramethyl-6-ch romanol and 2-[4,12-dimethyl-8-(trifluoromethyl)tridecyl]-2,5,7,8-tetramethyl-6-ch romanol

2-[4,8-Dimethyl-12-(trifluoromethyl)tridecyl]-2,5,7,8-tetramethyl-6-ch romanol and 2-[4,12-dimethyl-8-(trifluoromethyl)tridecyl]-2,5,7,8-tetramethyl-6-ch romanol, were synthesized by means of the Wittig reaction using the phosphonium salt of 2-(3-chloropr

The Cyclisation of Geraniol in Superacids

The cyclisation of geraniol (1) in FSO3H-SO2 at -78 deg C to yield the iridoid ether 3β,4α,6aα-trimethyl-cis-perhydrocyclopentafuran was investigated.Decomposition of the ether in FSO3H at room temperature gave the 2-isopropyl-1,3-dimethylcyclopentenium ion, whose structure was confirmed independently.Synthesis of geraniol labelled with deuterium on the gem-dimethyl group and on the single methyl group established the positions of these mehtyls in the iridoid ether.Synthesis of 2-(1-hydroxy-2,2-dimethylcyclopentyl)propan-1-ol established that the ion derived from it did not lie on the reaction pathway.
