A one-pot process for the regioselective synthesis of 1,3,4-trisubstituted-1H-pyrazoles

This Letter reports a facile and regioselective one-pot synthesis of 1,3,4-trisubstituted-1H-pyrazoles. It comprises a three-step telescoped sequence, which has been utilised in the production of a variety of differentially substituted pyrazoles.

Unambiguous synthesis of 1-methyl-3-hydroxypyrazoles

2,3-Dihydropyrazolo[3,2-b]oxazoles were used as intermediates in a new method for preparation of N1-methyl-3-hydroxypyrazoles. Synthesis of this bicyclic system was achieved either by alkylation of 3-hydroxypyrazole with 1,2-dibromoethane or, with better
