✦ Synopsis

Three pyridine derivatives, 4-(methoxymethyl)-6-methyl-2-oxo-1,2-dihydropyridine-3-carbonitrile (1), 4-(methoxymethyl)-6-methyl-5-nitro-2-oxo-1,2-dihydropyridine-3-carbonitrile (2) and 4-(methoxymethyl)-1,6-dimethyl-2-oxo-1,2-dihydropyridine-3-carbonitrile (3) have been synthesized, and their structural features have been studied by IR and electronic spectroscopy. The optical properties were investigated by UV-vis absorption and fluorescence spectroscopy. Fluorescence spectra of compounds have been recorded in two protic and two aprotic solvents in the range of 200-600 nm. The effects of substituents on the emission spectra of these compounds are interpreted. The structures of compounds 2 and 3 were also confirmed by single crystal X-ray diffraction method.

A series of N 4 -substituted oxadiazinanones have been synthesized from (1R,2S)-norephedrine by a process of either reductive alkylation or arylation, N-nitrosation, reduction and cyclization. These derivatives (R = -CH 2 Ph, -CH 2 C(CH 3 ) 3 , -cyclo-C 6 H 11 , -C 6 H 5 ) have been acylated with pr
