Abstract

The reaction of an acetyl-protected symmetrical sugar carbodiimide with amines yielded the corresponding trisubstituted guanidine derivatives 2-6 with two or three sugar units. Their tautomerism, isomerism and conformational behaviour were elucidated by application of one- and two-dimensional 1H and 13C NMR spectroscopy. The rate of tautomerisation was calculated from ROESY exchange measurements.
