Abstract
Substituted pyrazoline derivatives are synthesized in high yields through the cycloaddition reactions of azides with acrylates under Baylis-Hillman reaction conditions. Improved yields and enhanced rates are obtained using DABCO as the base.
Key words
azides - Baylis-Hillman reaction - cycloaddition reactions - pyrazolines
