SYNTHESIS AND ABSOLUTE CONFIGURATION OF THE ALANGIUM VITIENSE ALKALOID (-)-9-DEMETHYLTUBULOSINE

(-)-9-Demethyltubulosine has been sunthesized from the tricyclic amino acid (-)-IV through the intermediates (-)-V, (+)-VI, and (+)-VII.The identity of the synthetic (-)-I with a C28H35N3O3 base, isolated from Alangium vitiense, unequivocally esta

A SYNTHESIS OF (+/-)-9-DEMETHYLTUBULOSINE

(+/-)-9-Demethyltubulosine (I) has been synthesized from the tricyclic amino acid VII through the intermediates Viii, IX, and IV.Nonconformity of synthetic (+/-)-I with demethyltubulosine indicated the alternative 10-demethyl structure (V) to be the corre
