Acid-Mediated Three Component Assembly of 4-Fluoropyrazoles from α-Fluoronitroalkenes, Hydrazines, and Aldehydes

A new approach for the synthesis of highly pharmaceutically relevant 4-fluoropyrazoles via oxidative annulation of α-fluoronitroalkenes with in situ prepared hydrazones was developed. The reaction is efficiently promoted by trifluoroacetic acid while atmo

Synthesis of 3-(2-nitrovinyl)-4H-chromones: Useful scaffolds for the construction of biologically relevant 3-(pyrazol-5-yl)chromones

The Henry-type Barbier addition of bromonitromethane to 3-formylchromone, immediately followed by acetylation and concomitant elimination to afford nitroalkenes in excellent yield and total (E)-selectivity is described. Cycloaddition of N-methylhydrazones

Regioselective synthesis of 4-nitro- or 4-chloro-tetrasubstituted pyrazoles from hydrazones and β-halo-β-nitrostyrenes

We report an acid-catalyzed cycloaddition reaction of hydrazones with β-bromo- or β-chloro-β-nitrostyrenes for the regioselective synthesis of 4-nitro- or 4-chloro-tetrasubstituted pyrazoles. Arising from a common 4-halo-4-nitropyrazolidine intermediate,
