Abstract
One- and two-dimensional NOE and ROE experiments were applied to inves tigate the relative configuration at the stereogenic biaryl axes of na phthylisoquinoline alkaloids, natural biaryl compounds mainly occurrin g as stable atropisomers. The influence of ortho substitution at the b iaryl axes on the dynamic behavior of the atropodiastereomers and the determined NOE effects was investigated. As an example, the axial conf iguration of ancistrobrevine A was elucidated by the method. (C) 1997 by John Wiley & Sons, Ltd.
