    Opis:
    Some 4-aryl-5,6-dihydro-6-(substituted phenyl)-4H-1,3-oxazine- 2-amine derivatives including 4-(4-methyl-1-naphthyl)-5,6- dihydro-6-(substituted phenyl)-4H-1,3-oxazine-2-amines have been synthesised by hydroxyapatite catalyzed solvent-free cyclization of aryl chalcones and urea using microwave irradiation under solventfree condition. The yields of the oxazines were more than 85%. The synthesised oxazine amines have been characterized by their physical constants, analytical and spectroscopic data.

    Opis:
    About nine titled compounds were synthesized by greener method and the purities of these methanones have been examined using their analytical and spectral data reported in literature. The infrared and NMR spectral data of these methanones were assigned and correlated with Hammett substituent constants, F and R parameters using single and multi-linear regression analysis. From the results of statistical analyses, the effects of substituents in terms of spectral quantitative structure activity on the spectral frequencies were studied.

    Opis:
    A series of seven titled compounds have been prepared and their purities were examined by literature method. The characteristic infrared stretching frequencies (, cm-1) and the NMR chemical shifts (, ppm) of these anilines were assigned. These assigned spectral data were correlated with Hammett substituent constants, F and R parameters using single and multi-regression analysis. From the statistical results the effect of substituents on the spectral data have been discussed. The antimicrobial activities of these aniline derivatives have been evaluated by Bauer-Kirby disc-diffusion method.
