AbstractUvacalols are novel carbasugars isolated from the genera Uvaria. In this study, we report concise syntheses of (1R,2S,3R,6R)-6-ethoxy-4-(hydroxymethyl)cyclohex-4-ene-1,2,3-triol, a key intermediate for the synthesis of uvacalols I and J, and of its epimer (1R,2S,3S,6R)-6-ethoxy-4-(hydroxymethyl)cyclohex-4-ene-1,2,3-triol, starting from cheap and readily available methyl d-glucopyranoside.
