Polycyclic Aromatic Alkaloids, I. - Synthesis of Cleistopholine and SampangineCleistopholine (4) is prepared in a one-pot synthesis by Diels-Alder cycloaddition of 1 to 2, followed by thermal elimination of dimethylamine. Reaction of 4 with tripiperidinomethane or dimethylformamide diethyl acetal yields the enamines 5a/5b, which, without further purification, give sampangine (6) on heating with ammonium chloride in glacial acetic acid.
