Enantioselective bishydroxylation of the protected hydroxymethyl enynes 7a-d and 8a, b, which are easily obtained from commercially available 5 and 6, gave the triol derivatives 9a-d and l l a , b in good yields and moderate to high enantiomeric excess. Palladium-catalyzed coupling of 9a-d and l l a
