An efficient ultrasound-promoted synthesis of the Baylis-Hillman adducts catalyzed by imidazole and L-proline. | LitMetric

A convenient protocol was developed for the synthesis of the Baylis-Hillman adducts in the presence of weak Lewis base and l-proline at room temperature under ultrasound irradiation. This method provided the products in good to high yields (65-90%) and reasonable reaction times.
