Abstract
An enantioselective reduction and acetylation of esters to alpha-acetoxy et hers is described. Reduction with a NaAlH4-ephedrine reagent followed by in situ acetylation gives 2 with good enantiomeric excess. This reaction is l imited in scope, but it demonstrates that enantioselective reductions of es ters are possible. (C) 2000 Elsevier Science Ltd. All rights reserved.
