Regioselective synthesis of 1,3,5-Trisubstituted Pyrazoles from N-Alkylated Tosylhydrazones and terminal Alkynes

An efficient synthesis of 1,3,5-trisubstituted pyrazoles from Nalkylated tosylhydrazones and terminal alkynes was developed. The protocol was applied to a wide range of substrates and demonstrated excellent tolerance to a variety of substituents, includin

N-Alkylation of tosylhydrazones in the presence of triphenylphosphine

An efficient N-alkylation reaction of tosylhydrazones was developed in the presence of triphenylphosphine; triphenylphosphine played a key role in the transformation. A range of N-alkylated tosylhydrazones were prepared in good to high yields.
