✦ Synopsis
Treatment of pentoses and some hexoses with potassium cyanate in aqueous solutions, buffered with sodium dihydrogen phosphate or ammonium chloride, gave glycosylamine I ,2-(cyclic carbamates) {glycofurano(or pyrano)[l,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 acetylatedderivatives were character&d by ' H-and "C-n.m.r. spectrosco-PY.
