Diels-Alder Reactions of N-Alkenyl-Iminium Salts: A Novel Route to Indolizidine Derivatives

The Diels-Alder reaction of N-alkenyl-2-ethoxyiminium salts and simple alkenes gave Diels-Alder cycloadducts upon heating in nitromethane. Reduction of the intractable cycloadducts with hydride resulted in poor to moderate yields of indolizidine alkaloids.
