A series of pyrimidoquinazoline are prepared via the reaction of ethyl 2,2-dicyano-1-arylvinylcarbamate derivatives 1a-b with methyl 2-aminobenzoate, 1-(2-aminophenyl)ethanone and 2-aminobenzonitrile. The reactivity of compounds 1a-b toward 3-amino-4,6-diphénylnicotinonitrile are studied. The structures of the synthesized compounds are elucidated by X-ray diffraction, IR spectroscopy and nuclear magnetic resonance.

The nuclear magnetic resonance and mass spectral behavior of 5-phenyltetrazole, 5-p-nitrophenyl-tetrazole and the 1-methyl and 2-methyl derivatives of each have been determined. Characteristic differences between the spectra of the 1-methyl and 2-methyl isomers have been noted and found to be useful for the purpose of structural assignments. The synthesis of 1- and 2-methyl-5-phenyltetrazole containing 47.5 % of 15N in the 1- and 4-positions of the tetrazole ring aided interpretation of the mass spectra and also allowed measurement of a geminal and a vicinal 15N—H coupling constant.

The facile synthesis of 3,6-anhydro-5-deoxy-5-fluoro-1,2-O-isopropylidene-α-L-idofuranose (4) from readily available precursors is described. The 1H and 19F nuclear magnetic resonance spectra of this derivative have been analyzed. Interestingly, the fluorine substituent exhibits detectable spin coupling with all ring protons except H-2. Both of the anomeric 1,2-di-O-acetyl derivatives of (4) have also been studied.
