of the enantiomer of the structure, 1, assigned to the naturalproduct nobilisitine A has been accomplished using the enantiomerically pure cis-1,2-dihydrocatechol 4 as starting material. The 1H and 13C NMR spectral data derived from compound ent-1 do not match those reported for the naturalproduct, thus suggesting its structure has been incorrectly assigned.

The pentacyclic framework associated with the alkaloid (-)-lycorine (1) can be assembled in as few as six steps from the enantiomerically pure cis-1,2-dihydrocatechol 3 which is itself readily available on a large scale through the whole-cell biotransformation of bromobenzene. The methodology has been used in developing the first synthesis of compound 2, a derivative of lycorine.
