TL;DR: In contrast to previous reports that vincoside was the sole precursor for indole alkaloids in Vinca rosea, the 3α epimer strictosidine has been incorporated into tetrahydroalstonine, ajmalicine, catharanthine and vindoline; the anomalous 3β to 3α inversion is no longer required.

TL;DR: Heteroyohimbine alkaloids, akuammigine and 3-isorauniticine, were synthesized using a modified Polonovski reaction followed by NaCNBH3 reduction from desmethylhirsuteine N-oxide as mentioned in this paper.
Abstract: Heteroyohimbine alkaloids, akuammigine and 3-isorauniticine, were synthesized using a modified Polonovski reaction followed by NaCNBH3 reduction from desmethylhirsuteine N-oxide, which was derived from the indole alkaloid hirsuteine Corynanthe alkaloid, corynantheidine was also synthesized using the same method from hirsuteine N-oxide
