Abstract
Highly stereoselective epoxidations have been achieved in both cyclohexylidene acetal and butane 2,3‐bisacetal (BBA) protection of (1,4,5)‐cyclohex‐2‐ene‐triols. These epoxy derivatives are all derived from D‐(−)‐quinic acid and can be used for the synthesis of muco‐, (+)‐epi‐, (+)‐vibo, (−)‐talo, and (−)‐gala‐quercitols.
