Sparsiflorine was originally isolated as a white amorphous powder, C17H17O3N (mp 230°-232° decomp.), from the leaves of the shrub Croton sparsiflorus Morung (Euphorbiaceae) (4) hydrochloride (mp 283°-284° decomp.), hydrobromide (mp 276°-278° decomp.), oxalate (mp 265°-267° decomp.), and picrate (mp 225°). The alkaloid was found to contain one methoxyl, three active hydrogens, and no methylenedioxy or A -methyl group. [Pg.3]

Aporphine Alkaloids.—The biosynthesis of the proaporphine and aporphine alkaloids of Croton sparsiflorus has been investigated and found to be unexceptional. Thus [2- C]tyrosine was found to be a precursor for crotsparine (74), crotsparinine (75), and sparsiflorine (76). Moreover, labelled ( )-coclaurine (77), but not ( )-isococlaurine (78), was found to give radioactive alkaloids. Coclaurine was also shown to be present in C. sparsiflorus by means of a trapping experiment using [2- C]tyrosine and inactive coclaurine radioactive coclaurine was isolated at the end of the experiment.
