A wide array of polysubstituted 1-bromo and chloronaphthalenes are obtained from coupling of allylbenzenes and polyhalomethanes. The reaction is mediated by iron metal under visible light irradiation and proceeds via a Kharasch addition intermediate followed by intramolecular FeIII mediated Friedel-Crafts alkylation, with the formation of two Csp2?Csp2 bonds in the process. This method gives easy access to 1-halonaphthalenes with substituent(s) at C-5 to C-8 that are otherwise hard to synthesize. (Figure presented.).

Page/Page column 43-44, (2010/11/26)
The present invention relates to a 9-azabicyclo[3.3.1]nonane derivative of formula (I), wherein R1 is H or C1-5alkyl; X is O or NR2, wherein R2 is H, C1-5alkyl or C2-5acyl and Ar is C6-10aryl or a 5-10 membered heteroaryl ring system, both being optionally substituted with one to three of R3-R5 independently selected from halogen, C1-5alkyl, C1-5alkoxy, C3-6cycloalkyl, C2-5alkenyl, C2-5alkynyl, CN, NO2, hydroxy, phenyl, phenoxy and phenylC1-2alkoxy, wherein said C1-5alkyl and C1-5alkoxy are optionally substituted with one to three halogens and wherein said phenyl, phenoxy and phenylC1-2alkoxy are optionally substituted with one to three substituents independently selected from halogen and methyl or two of R3-R5 at adjacent positions together form a methylenedioxy or propylene unit, with the proviso that the compounds exo-9-methyl-3-phenoxy-9-azabicyclo[3.3.1]nonane and N-(9-methyl-9-azabicyclo[3.3.1]non-3-yl)-1H indazole-5-amine are excluded, or a pharmaceutically acceptable salt or solvate thereof. The invention also relates to pharmaceutical compositions comprising said 9-azabicyclo[3.3.1]nonane derivatives and to their use in therapy.

New chiral synthons from the microbial oxidation of bromonaphthalenes
Hudlicky, Tomas,Endoma, Mary Ann A.,Butora, Gabor
, p. 61 - 68 (2007/10/03)
1-Bromo- and 2-bromonaphthalene were subjected to bio-oxidation with whole cells of Pseudomonas putida NCIB 9816-11. The major metabolites were isolated and spectroscopically characterized as (+)-cis-(1R,2S)-Dihydroxy-1,2-dihydro-8-bromonaphthalene 1, (+)-cis-(1R,2S)-Dihydroxy-1,2-dihydro-5-bromonaphthalene 2 from 1-bromonaphthalene and (+)-cis-(1R,2S)-Dihydroxy-1,2-dihydro-7-bromonaphthalene 8 from 2-bromonaphthalene. The absolute stereochemistry and enantiomeric excess were determined by conversion of each metabolite to the known (-)-cis-tetrahydronaphthalene diol 6.
The Baeyer-Villiger Oxidation of Aromatic Aldehydes and Ketones with Hydrogen Peroxide Catalyzed by Selenium Compounds
Syper, Ludwik
, p. 167 - 172 (2007/10/02)
A series of organoselenium compounds was investigated as activators of hydrogen peroxide in the Baeyer-Villiger oxidation.As a result, a convenient and cheap method for transformation of aromatic aldehydes, having polycondensed ring systems or electron-donating substituents, and polymethoxy derivatives of acetophenone, into phenols was elaborated.This method utilizes hydrogen peroxide activated by areneseleninic acids, as oxidizing agent.
