title: Synthesis of N-bridgehead heterocycles from saccharide benzimidazoles.
abstract: Treatment of D-arabino-tetritol-1-yl-benzimidazole with P-toluenesulfonyl chloride (1molequiv) in pyridine, afforded the N-bridgehead heterocycles, 2R,3R,4S-trihydroxy-1:2:3:4-tetrahydropyridino[1,2-a]benzimidazole. The structure of the latter compound was determined by acylation, (1)H, and (13)C NMR spectroscopy and mass spectrometry.
