In order to investigate the biological activity of novel bis-pyrazole compounds, a series of N-(3-alkyl-5-(N-methylcarbamyl)-1H-pyrazol-4-yl)-3-alkyl-4-substituted-1H-pyrazole-5-carboxamides were designed and synthesized with ethyl 3-alkyl-1H-pyrazol

Pyrazolo[3,4- b]pyridines have been obtained by the condensation of 5-amino-4-cyanopyrazole, readily available by the reaction of dithioacetals with substituted hydrazines, with β-ketoesters or β-diketone in the presence of tin(IV) chloride at refl

Six novel 12-alkoxycarbonylmethylene-1,15-pentadecanolides ( 3 ) were synthesized from 2-nitrocyclo-dodecanone by the Michael addition with acrolein followed by ring enlargement, Nef reaction and Wittig–Horner reaction. Their structures were confir
