The reaction of tryptamine with δ-valerolactone in tetralin gave δ-hydroxyamide (3) as the main product and the lactam (4) as the minor product. However, the reaction of 5, 6-dihydro-2-pyrone with tryptamine or aniline afforded a mixture of the corresponding αβ- and βγ-unsaturated lactams, whereas, 2-pyrone did not react with either tryptamine or aniline to give the corresponding pyridone. Cyclization of 3 or 4 by Bischler-Napieralski reaction and followed NaBH<SUB>4</SUB> reduction provided a convement synthesis of 1, 2, 3, 4, 6, 7, 12, 12b-octahydroindolo [2, 3-α] quinolizine (23).
