Abstract

The reaction of an acetyl‐protected symmetrical sugar carbodiimide with amines yielded the corresponding trisubstituted guanidine derivatives 26 with two or three sugar units. Their tautomerism, isomerism and conformational behaviour were elucidated by application of one‐ and two‐dimensional ^1^H and ^13^C NMR spectroscopy. The rate of tautomerisation was calculated from ROESY exchange measurements. Copyright © 2001 John Wiley & Sons, Ltd.

A dynamic NMR study of the tautomerism of 2,2'-bisbenzimidazolyl in DMSO-d 6 and a mechanistic interpretation of the process, based on a stepwise, single-proton transfer and formation of a zwitterionic intermediate, are presented. This interpretation is substantiated by semi-empirical calculations o

The possible tautomeric equilibria of benzofuroxan and its sulphur and selenium analogues were examined by multinuclear NMR methods. The 1 H, 13 C, 14 N and 15 N NMR signal assignments were achieved largely by 2D methods and some older nitrogen NMR data were verified. At room temperature and above,

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 unequivocal
