A convenient liquid-phase synthetic protocol for the construction of structurally
diverse 2,3-dihydro-4-pyridones on soluble polymer support by the aza Diels-Alder
reaction has been developed, which utilized a one-pot three-component reaction of
either PEG-supported amine, aromatic aldehydes and the Danishefsky’s diene, or PEG-supported
aldehyde, aromatic amines and Danishefsky’s diene.
