Treatment of pentoses and some hexoses with potassium cyanate in aqueous solutions, buffered with sodium dihydrogen phosphate or ammonium chloride, gave glycosylamine 1,2-(cyclic carbamates) {glycofurano(or pyrano)[1,2-d]oxazolidin-2-ones}. Most of the products had furanoid structures, but d-mannose and d-lyxose gave preponderantly pyranose derivatives. Epimerisation at C-2 was observed in certain reactions. The products and their acetylated derivatives were characterised by 1H- and 13C-n.m.r. spectroscopy.
