1- Acetyl-2-hydroxy naphthalene

The (+H, 2-epoxides of naphthalene (138) and anthracene (137) can be prepared using a similar sequence from the corresponding (—)-menthoxy-acetyl derivatives of frans-2-bromo- 1-hydroxy-1,2,3,4-tetrahydronaph-thalene and anthracene, whereas the (—)-epoxides (136 and 139) are obtainable from the (+ )-menthoxyacetyl derivatives.67 The configurations of these compounds are determined by NMR analyses and correlation with alcohols of known configuration. Solid oxide 138 is unstable, whereas... 

Naphthalene 1,2-oxide. Yagi and Jerina have reported a new method for synthesis of arene oxides. The starting material for the preparation of naphthalene 1,2-oxide (5) is I-hydroxy-2-bromotetralin, (I), which is acetylated with irifluoroacctic anhydride in chloroform to give (2) in 84 % yield. This is converted into the dibromide (3) by treatment with NBS (note that tetralin 1,2-epoxidc is uiLstable to bromination with NBS). The... 

The infrared spectrum of quinazoline and other diazanaphthalenes were measured, and the vibrational fundamentals were assigned from Raman polarization data. The Raman spectrum of quinazoline in aqueous solution has fourteen bands that appear to be polarized. All the band frequencies, except for those at 1330 and 1334 cm were consistent with the frequencies assigned as fundamentals in the spectrum of naphthalene. The infrared spectra of several quinazolin-4(3H)-ones and their 3-acetyl, 3-acetoxy, and 3-hydroxy derivatives were examined at wave numbers lower than 3000 cm Bands due to NH stretching vibrations provided evidence for cyclic dimeric association between molecules. The zwitterionic structure (3) was proposed for 3-hydroxyquinazolin-4-one. ... 

Reaction between full (2,3-2-0-acetyl-6-deoxy-6-iodine)-/3-CD and 6-hydroxy-2-naphthalene carboxylic acid methyl ester could generate the whole (2,3-di-0-acetyl-6-0-2-naphthyl methyl)-/S-CD in the NaH/DMF solution [10].
