A simple, highly efficient, and environmentally friendly method for the synthesis of substituted 1H-pyrazoles by one-pot condensation reaction of α,β-unsaturated carbonyl compounds with tosyl hydrazide in water was developed. The reaction system exhibited tolerance with various functional groups, Aromatic moiety with both electron-rich and electron-deficient substituents could give desired products

An efficient method for the construction of various pyrazolo[5,1-a]isoquinolines has been achieved via Ru(II)-catalyzedα-carbonylsulfoxoniumylide annulations with aryl substituted pyrazoles. This oxidant-free transformation occurred through pyrazole-directed C–H activation, Ru-carbene insertion, and acid-promoted carbonyl condensation processes, enabling dual C–C and C–N bond formation.
