Article abstract of DOI:10.1002/jhet.5570340529

The reaction of 1-acyl-3,5-dimethyIpyrazoles 1 with C=N compounds was kinetically controlled with syn stereoselectivity through a lithium enolate intermediate using lithium diisopropylamide. In contrast, the anti stereoselective reaction of 1 was caused b
