Imines have been used as heterodienophiles in inter- and intramolecular Diels-Alder reactions. The reaction conditions depend on the nature of the substituents on the imine. Simple, neutral imines need the presence of Lewis acids to react with electron-rich dienes. For leading references, see: Weinreb, S. M. Heterodienophile Additions to Dienes in Comprehensive Organic Synthesis; Trost, B. M., Fleming, I., Eds.; Pergamon Press: Oxford, UK, 1991; Vol. 5, pp 401-449.
