Spiroannulation approach to pentalenene, an angular triquinane sesquiterpene
Wu,Zhu,Burnell
, p. 104 - 110 (1994)
The route to the angular triquinane (±)-pentalenene (1a) followed from an efficient geminal acylation of the acetal of isophorone or its homolog 6b by 1,2-bis((trimethylsilyl)oxy)cyclobutene (3) in the presence of boron trifluoride etherate. Ring cleavage
Iron Catalyzed Highly Enantioselective Epoxidation of Cyclic Aliphatic Enones with Aqueous H2O2

An iron complex with a C1-symmetric tetradentate N-based ligand catalyzes the asymmetric epoxidation of cyclic enones and cyclohexene ketones with aqueous hydrogen peroxide, providing the corresponding epoxides in good to excellent yields and enantioselectivities (up to 99% yield, and 95% ee), under mild conditions and in short reaction times. Evidence is provided that reactions involve an electrophilic oxidant, and this element is employed in performing site selective epoxidation of enones containing two alkene sites.
The coupling of butylvinyltellurides with organometallic reagents catalysed by nickel complexes
Raminelli, Cristiano,Gargalaka Jr., Jo?o,Silveira, Cláudio C.,Comasseto, Jo?o V.
, p. 8801 - 8809 (2008/02/10)
Vinylic tellurides couple efficiently with sp, sp2 and sp3 hybridised organometallic compounds (Li, MgX and Zn species) in the presence of dichloro-bis(triphenylphosphine)nickel(II) as catalyst.
Zur Photospaltung konjugierter γ,δ-Epoxyenone. UV.-Bestrahlung von 3-(1',2'-Epoxy-2'-methyl-prop-1'-yl)-5,5-dimethyl-2-cyclohexen-1-on
Weck, Guy de,Wolf, Hans Richard
, p. 224 - 234 (2007/10/02)
On 1?,?*-excitation (λ=254 nm) 9 undergoes cleavage of the C(γ),C(δ)-bond yielding 17 and a, which gives 18 by photofragmentation.In presence of maleinic ester the photolysis of 9 yields 20, in the presence of methanol 21 and 22 are
