An enantioselective synthesis of the structure, 3, assigned to the alkaloid (+)-montabuphine has been achieved using the readily available metabolite 4 as starting material. A comparison of the physical and spectral data recorded on compound 3 with those reported for (+)-montabuphine suggests that they are different compounds.

over-express the responsible enzyme, namely toluene dioxygenase. Since the enantiomer of compound 3 is available by related means, the present work also represents a formal total synthesis of the montanine alkaloid (−)-nangustine [(−)-2]. Single-crystal X-ray analyses of compounds 13 and (+)-2 are reported.
