An efficient, one-potsynthesis of substituted pyrazoles from enones, hydrazides, and halides was developed. In comparison with the classical Knorr pyrazolesynthesis, this methodology gave a different type of product (R3≥R5). A range of substituted pyrazoles were prepared in good to high yields with complete regioselectivity.
