Abstract 7-Formyl-5-methyl-5, 6-dihydroindolizine and 7-formyl-6-methyl-5, 6- dihydroindolizine were obtained via a domino hydroformylation/cyclization/dehydration reactions sequence starting from the corresponding 1-allyl-2-formylpyrroles. An intramolecular aldol condensation between the carbon atom adjacent to the formyl group in the chain of the produced aldehydes and the carbonyl group directly bonded to the pyrrole ...
