A facile synthesis of (±)-corynantheidol (17) has been achieved by the application of enamine annelation using 3,4-dihydro-1-methyl-β-carboline (5) and dimethyl 3-methoxyallylidenemalonate (6). Stereochemical assignment for catalytic hydrogenation products of the corresponding enamides has also been investigated.
