Abstract
The syntheses of methyl-and phenyl-substituted 2H-pyrroles 8 bearing a but-3-enyl or pent- 4-enyl side chain are reported. The thermolyses of 8 yielded tricyclic derivatives with the 2- azabicyclo [2.2. l] hept-2-ene moiety resulting from the intramolecular Diels-Alder additions of 3H-pyrrole intermediates. No product resulting from the intramolecular cycloaddition of 2H- pyrroles or of 1H-pyrroles was observed. Thermochemical analysis and ab initio STO-3G ...
