A Strategy for the Synthesis of Anthraquinone-Based Aryl-C-glycosides

An efficient and simple strategy for the synthesis of a diverse range of anthraquinone-based aryl-C-glycosides has been developed. It involves the sequential Diels-Alder reaction and oxidative aromatization with the preformed glycosyl diene and dienophiles. The glycosyl dienes were obtained from simple sugars by tandem one-pot substitution and elimination reaction.
