A photocatalytic synthesis of homoallyl ketones was achieved via a one-pot procedure starting from a Norrish Type I reaction of cyclopentanones, followed by a decatungstate-catalyzed hydroacylation of electron-deficient olefins by the resulting 4-pentenals. The site-selective formyl H-abstraction in the second step can be explained by radical polar effects in the transition state.
Cohalogenation of alkenes in ethylene oxide: Efficient methodology for the preparation of allyl vinyl ether precursors of γ,δ-unsaturated aldehydes
Dulcere,Rodriguez
, p. 399 - 405 (2007/10/02)
An investigation of the cohalogenation-dehydrohalogenation sequence as a method for the preparation of allyl vinyl ethers from simple olefins has been performed. Alkenes 1a-k react with bromide or chloride in the presence of ethylene oxide at -80°C to for
INTRAMOLECULAR N-ALKENYLNITRONE-ADDITIONS. REGIO- AND STEREOCHEMISTRY
Oppolzer, W.,Siles, S.,Snowden, R. L.,Bakker, B. H.,Petrzilka, M.
, p. 3497 - 3509 (2007/10/02)
Efficient intramolecular cycloadditions of N-3-alkenyl- and N-4-alkenylnitrones proceed with opposite regioselection which is modified by dipolarophile-substituent effects.Polycyclic isoxazolidines are obtained in a highly stereocontrolled fashion, consistent with an endo-addition of the Z-nitrones.
PHOTOLYSIS OF THE AZOALKANE 2,3-DIAZATRICYCLO4,9>NON-2-ENE: DIRECT OBSERVATION OF 4-CYCLOHEXENYLDIAZOMETHANE

Besides denitrogenation to the tricycloalkane 8, the photolysis of azoalkane 3 affords the diazoalkane 4, which serves as precursor to the minor hydrocarbon products 9, 10 and 11; irradiation of azoalkane 3 with the 333.6 nm line of an 18-W argon ion laser was essential to obtain preparative quantities of diazoalkane 4 for its detection and identification.
