A novel synthetic path to 1,3‐disubstituted pyrazoles, 4,5‐dideuteropyrazoles and 5‐deuteropyrazoles based on the interaction of the readily available vinyl ethers and in situ generated nitrile imines was developed. The joint experimental and computational study clarified the mechanism of the process and allowed us to propose a convenient access to regioselectively deuterated pyrazoles.
