Sterically hindered 2,4-disubstituted 3-(5-tetrazolyl)pyridines were synthesized from corresponding nicotinonitriles using microwave technology. 2-Methylnicotinonitriles were converted into the 2-azidomethyl-3-cyanopyridines via 2-hydroxymethyl and 2

2,4,7-Trisubstituted hydrogenated pyrazino[1,2-a]pyrazines as potential β-turn mimetics were prepared for the first time in a stereoselective synthesis from hexahydro[1,2,3]triazolo[1,5-a]pyrazines.

A solution-phase synthesis for the preparation of substituted 2-(1,2,4-triazol-3-yl)benzimidazoles from triazole aldehydes and ortho-phenylenediamines has been developed for the purpose of producing diverse lead generation libraries. Crude products w

An intramolecular [2+3]-cycloaddition of an azide to a C C double bond was carried out to obtain hexahydro[1,2,3]triazolo[1,5- a ]pyrazines. These compounds were used as intermediates to prepare 2-(halogenomethyl)piperazines that could serve as precu

2-Methyl-3-cyanopyridines were converted into the corresponding 2-azidomethyl derivatives, which then underwent an intramolecular cycloaddition reaction. A novel heterocyclic system containing a 3-(tetrazol-5-yl)pyridine unit was obtained in this way
