A hetero Gels-Alder route to 5,6-dihydro-y-pyridones is described. Recently, we described the Lewis Acid catalyzed cyclocondensation of aldehydes with siloxydienes to give 5,6-dihydro-y-pyrones. It was of interest to attempt to extend this reaction to include the imino linkage. Certainly, there have
