The aza Diels-Alder reaction is described for a novel diene. Imines bearing benzyl and aromatic protecting groups both work well. Moderate diastereoselectivities can be obtained using the simple alpha-methylbenzyl chiral auxiliary. (c) 2005 Elsevier Ltd. All rights reserved.

A highly efficient procedure for the synthesis of 2-substituted-2,3-dihydro-4-pyridone derivatives through the aza-Diels-Alderreaction under 'green chemistry' conditions is described. The reaction of Danishefsky'sdiene with imines has been found to perform better at room temperature in ionic liquids without an acid catalyst and organic solvent: the ionic liquids are recycled while their efficiency
