Enantioselective Total Synthesis of (−)‐Diversonol

Chemistry – A European Journal, 2013
AbstractFor the synthesis of (−)‐diversonol (ent‐1), an enantioselective domino‐Wacker/carbonylation/methoxylation reaction and an enantioselective Wacker oxidation were used to give the chroman in high yield and 96 % and 93 % ee, respectively. Dihydroxylation at the vinyl moiety using the Sharpless procedure and a Wittig–Horner reaction followed by ...
