Abstract:
A selective synthesis of acrylamides had been developed using the Doebner-Knoevenagel condensation. The reaction occurs under mild conditions at ambient temperatures, tolerates a wide array of functional groups, and affords the E-isomer with high selectivity. The reported method expands the scope of this classic reaction to a class of industrially important products and as well as to the use of aliphatic aldehydes. An organocatalytic mechanism has been proposed, and the ability to scale the process has been demonstrated.

Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
