## Abstract The conjugate additions of __N__‐(α,β‐unsaturated)acylpyrazoles were carried out by the treatment with Grignard reagents in the presence of cuprous halides. The reaction of 2‐(α,β‐unsaturated)acyl‐3‐phenyl‐__l__‐menthopyrazoles 3a‐h occurred in higher chemical yields and with asymmetric
