Synthesis of Hexoses Derivatives Containing N=O Group

Ivane Javakhishvili Tbilisi State University, I.Chavchavadze av. 3 Modification of carbohydrates by various types of organic compounds has recently played a significant role in the synthesis of new of biological snd pharmacologically active compounds. Little has been published about carbohydrates containing nitrozo group. The application of glycosides for the modification of biologically active organic compounds, on the one hand, change their biological and physiological action, and on the other, may reduce their toxicity. The goal of present investigation consist in synthesis of N-glycosides containing nitrosogroup. The reaction condensation of N-p-carboxyphenyl--D-gluco(galacto)pyranozilamine with N,N'-Dicyclohexylcarbodiimide in the prezenc of tetrahydrofuran and triethylamine was studied for the ferst time. By interaction of obtained N-acylureas with sodium nitrite corresponding nitrosoderivatives have been received Ivane Javakhishvili Tbilisi State University, I.Chavchavadze av. 3 Modification of carbohydrates by various types of organic compounds has recently played a significant role in the synthesis of new of biological snd pharmacologically active compounds.
