H. Takayama et al., Isolation, partial synthesis and stereochemical study of 10-hydroxystrictosamide, a constituent of Nauclea orientalis in Thailand, HETEROCYCLE, 49, 1998, pp. 49-52
From the Rubiaceous plant, Nauclea orientalis, in Thailand, seven non-alkal
oidal and two glycosidic indole compounds were isolated. 10-Hydroxystrictos
amide (5) and its pentaacetyl derivative (11) were prepared to determine th
e C3 stereochemistry.
