Anti‐infective dimers! A source of stereochemically and pharmacologically exciting metabolites: The Chinese plant Ancistrocladus tectorius. The alkaloids have as many as three consecutive chiral axes and show specific anti‐infective activities. The Chinese characters mean “plant with hooks” (=Ancistrocladus). For further information see the Full Paper by G. Bringmann et al. on page 4206 ff.
Five novel dimeric naphthylisoquinoline alkaloids, shuangancistrotectorines A (3 a), B (3 b), C (4), D (5 a), and E (5 b), have been isolated from the twigs of the Chinese plant Ancistrocladus tectorius. Their absolute stereostructures were determined by spectroscopic and chiroptical methods in combination with quantum chemical CD calculations. In contrast to all other known dimeric naphthylisoquinoline...
