摘要
Several Baylis-Hillman adducts were prepared by the reaction of appropriate arylaldehydes with methyl vinyl ketone in the presence of imidazole and a catalytic amount of L-proline, in 55-90% yields. An easy transformation of these adducts into 1,5-diarylpyrazoles was achieved using microwave irradiation ( 400 W) with short reaction times (1-3 min) and high yields (80-91%).
