Synthèse énantiospécifique du (−)‐(1R, 3R, 5S)‐diméthyl‐1,3‐dioxa‐2,9‐bicyclo[3.3.1]nonane

Abstract
Enantiospecific Synthesis of (−)‐(1R, 3R, 5S)‐1,3‐Dimethyl‐2,9‐dioxabicyclo[3.3.1]nonaneThe isomer (−)‐(1R, 3R, 5S)‐endo‐1,3‐dimethyl‐2,9‐dioxabicyclo[3.3.1]nonane ((1R, 3R, 5S)‐8) has been synthesized from (−)‐(3R)‐methyl 3‐hydroxybutanoate. The key intermediate (3R, 5R)‐5 is proved to be a useful synthon for EPC syntheses.
