An improved synthesis of pyrazolines from aryl azides and acrylic esters
Yadav,Subba Reddy,Geetha
, p. 513 - 515 (2002)
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.
