3-Aryl-5-isoxazolecarboxaldehyde undergoes fast Baylis-Hillman reaction with a variety of activated alkenes to yield the corresponding adducts in excellent yields. Some of the Baylis-Hillman adducts reported herein have been subsequently modified to obtain isoxazole substituted pyrazolin-3-ones and γ-butyrolactones.
