[On the Constituents of Isertia hypoleuca.].
Dihydroquinamine and 3-epi-dihydroquinamine were isolated and identified from ISERTIA HYPOLEUCA (Schultes, Rauffauf and Soejarto 24041). The structure of hydroxydihydrocinchonamine, a reduction product from dihydroquinamine with LiAlH (4), was established. The (13)C magnetic resonance spectra of the three alkaloids have been determined.
