Abstract
R(+)- and S(-)-1, 2, 3, 4, 6, 7, 12, 12b-Octahydroindolo [2, 3-α] quinolizine (IIIa, b), and R(+)- and S(-)-5, 7, 8, 13, 13b, 14-hexahydrobenz [b] indolo [2, 3-α] quinolizine (IVa, b) were synthesized by the application of the Fischer indole synthesis on optically active hexahydro-2H-quinolizin-1(6H)-one (Ia, b) and 3, 4, 11, 11a-tetrahydro-2H-benzo [b] quinolizin-1(6H)-one (IIa, b) of known absolute configuration.
