Description
Gitingensine is a steroidal alkaloid which occurs in Kibatalia gitingensis, being
found mainly in the leaves. It is optically active with a specific rotation of [α]
31D
- 65° (CHCI3). The hydrochloride has m.p. 281°C; [α]
23D - 59.8° (CHCI3) and
is more readily obtainable in the pure form than the free base. Deamination of
the alkaloid by diazotization gives the deamino derivative, m.p. 235°C. The amino
group may be methylated to yield the N-methyl compound, m.p. 223-4°C but
the base cannot be methylated further.
