Synthesis of C‐Arylglycosides via Ru(II)‐Catalyzed [2 + 2 + 2] Cycloaddition.

Abstract

Synthesis of C-Arylglycosides via Ru(II)-Catalyzed [2 + 2 + 2] Cycloaddition. -In the presence of a Ru-catalyst, the cycloaddition of 1,6-diynes with various C-alkynylglycosides proceeds at ambient temperature to afford the title compounds, such as (III), (V), (VII), (IX) and (XI). -(YAMAMOTO*, Y.; SAIGOKU, T.; OHGAI, T.; NISHIYAMA, H.; ITOH, K.; Chem.
