## Abstract Starting from 1__H__‐pyrazol, a wide number of 1‐alkyl‐1__H__‐pyrazol‐4‐yl and 1‐alkyl‐1__H__‐pyrazol‐5‐ylboronic acids and their pinacol esters were synthesized and characterized. The key step in the described methodology is the regioselective lithiation of the pyrazole ring. The synth
