Abstract

The (1)H and (13)C NMR spectra of two stereoisomeric bis-Tröger's bases and four stereoisomeric tris-Tröger's bases asymmetrically substituted on the external aromatic rings were recorded and the corresponding signals assigned. The relative configuration of the stereogenic units has been unequivocally determined on the basis of homoallylic couplings and NOE experiments.Copyright (c) 2005 John Wiley & Sons, Ltd.
