Synthesis and NMR analysis of spiranic heterocycles from carbohydrate derivatives
(Chemical Equation Presented) We report the synthesis of some furanose and pyranose acylhydrazones and their heterocyclization products. The new compounds were characterized physically and spectroscopically and the syn-anti and (R)-(S) configuration was determined by NOESY experiments. We discuss th...
