Gelselegine

The isolation of gelselegine (56) and ll-methoxy-19(R )-hydroxygelselegine (57) (Table 10), new types of oxindole alkaloids having a hydroxymethyl group at the C-20 position in the gelsedine skeleton, was reported (57). [Pg.483]

The second gelselegine-type new alkaloid, ll-methoxy-19(i )-hydroxygelselegine (57), has two more oxygen substituents compared with gelselegine itself. Including the new asymmetric center at the C-19, the structure of 57 was determined by X-ray analysis. [Pg.485]

In turn, an other member of the gelselegine-type compounds having 19-hydroxy group was also prepared stereoselectively from the same... [Pg.511]
