Pyrazolo[3,4-d][1,2,3]triazolo-1-carboxamides and 5-alkylaminopyrazolo[3,4-d]oxazoles: Synthesis and evaluation of the in vitro antifungal activity

A series of N-alkyl-N'-(4-diazo-5-pyrazolyl)-ureas (4) was thermally and photochemically converted into pyrazolo [3,4-d][1,2,3]triazole derivatives (5,6) and 5-alkylaminopyrazolo[3,4-d]oxazoles (7) respectively. The products were tested for in vitro antif

SYNTHESIS OF N-ALKYL-N'-(4-DIAZO-5-PYRAZOLYL)UREAS AND THEIR CONVERSION INTO PYRAZOLOTRIAZOLE AND PYRAZOLOOXAZOLE DERIVATIVES

The synthetic route to N-alkyl-N'-(4-diazo-5-pyrazolyl)ureas (4) srarting from pyrazolooxadiazin-3(5H)-one (1) is described.Compounds (4) undergo thermal and photochemical reactions affording pyrazolotriazoles (5) and pyrazolo
