The development of a continuous flow procedure using silica-supported copper catalysts for the preparation of trans-4,5-diamino-cyclopentenones from furfurals and secondary amines under Lewis acid catalysis has led to high efficiency and recyclability for a broad scope of cyclic enones.
The formation of cyclopentenones from biomass derivatives has been developed by reacting furfurals with secondary amines using Lewis acid catalysis under batch conditions. The challenge of scaling up these processes leads to the development of a continuous flow procedure for the preparation of trans-4,5-diamino-cyclopentenones using silica-supported copper catalysts. These catalysts exhibited high efficiency and recyclability for the preparation of a broad scope of cyclic enones.
