Synthesis of <i>N</i>‑Heteroaryl <i>C</i>‑Glycosides\nand Polyhydroxylated Alkanes with Diaryl\nGroups from Unprotected Sugars

HCl-catalyzed <i>C</i>-glycosylation was described\nherein\nfor the convenient preparation of <i>N</i>-heteroaryl <i>C</i>-glycosides and polyhydroxylated alkanes with diaryl groups\nusing hetereoaryl amines and unprotected sugars as starting materials.\nThe reaction temperature and the amounts of aryl amines and HCl had\nsignificant effects on reactions. The method provided a highly efficient\nand environmentally friendly route for constructing <i>C</i>-glycosides at low cost.
