The vanadium-dependent chloroperoxidase from Curvularia inaequalis is a stable and efficient biocatalyst for the hydroxyhalogenation of a broad range of alkenes into halohydrins. Up to 1 200 000 TON with 69 s-1 TOF were observed for the biocatalyst. A bienzymatic cascade to yield epoxides as reaction products is presented.
Synthesis of 2,6-disubstituted piperidine alkaloids from ladybird beetles Calvia 10-guttata and Calvia 14-guttata

Optically pure (+)-calvine, (+)-2-epicalvine, (2S,6S)-(6-pentylpiperidin-2-yl)acetic acid methyl ester and (2R,6S)-(6-pentylpiperidin-2-yl)acetic acid methyl ester, four piperidine alkaloids isolated from ladybird beetles of the genus Calvia (Coccinellidae), were synthesised from a common precursor using cyclisative Pd(II)/Cu(II)-catalysed carboamination-(methoxy)carbonylation tandem reaction of alkenylamines as a key step. The first single-crystal X-ray analysis of (+)-calvine confirmed its proposed absolute configuration to be (2S,6S) corresponding to that of natural product.
Micellar Effects upon Alkene Bromination. 2. The Role of Alkene Hydrophobicity
Cerichelli, Giorgio,Grande, Celeste,Luchetti, Luciana,Mancini, Giovanna
, p. 3025 - 3030 (2007/10/02)
Surface polarity of cettyltrimethylammonium bromide (CTAB) aqueous micelles was checked by use of as a probe the bromination reaction of a series of 1-alkenes and a water-soluble alkene, cis-4-cyclohexene-1,2-dicarboxylic acid dimethyl ester (I).There was
A Short and Efficient Synthesis of 4,5-Disubstituted-1-pentenes
De Camp Schuda, Ann,Mazzocchi, Paul H.,Fritz, Gregory,Morgan, Tina
, p. 309 - 312 (2007/10/02)
A one step synthesis of 5-chloro-4-hydroxy-1-pentene (65percent) and 5-bromo-4-hydroxy-1-pentene (81percent) was developed.Treatment of epibromohydrin or epichlorohydrin at -73 deg C with a reagent prepared from vinylmagnesium bromide and a catalytic amount of copper(I) bromide gave the desired products. 5-Bromo-4-hydroxy-1-pentene in was cleanly converted to 4,5-epoxy-1-pentene in 99percent yield by treatment with potassium hydroxide.A number of derivatives of 5-bromo-4-hydroxy-1-pentene are described.
