Enantiopure representatives of the title heterocyclic systems, which are of interest in alkaloid chemistry, are accessible by a procedure based upon intramolecular cycloadditions of nitrones derived from N-(cyclohex-2-enyl)-substituted pyrrole-2- and indole-2-carbaldehyde, followed by reductive manipulation of the cycloadducts.
