<jats:title>Abstract</jats:title><jats:p>A highly efficient and diastereoselective synthesis of the C1–C11 fragment of the marine natural product (+)‐peloruside A has been developed. Through enzymatic desymmetrization of diethyl 3‐hydroxyglutarate with lipase B from <jats:italic>Candida antarctica</jats:italic> a large‐scale access to enantiomerically highlyenriched starting material was achieved. Subsequent stereogenerating key steps utilized in the synthesis were a Sharpless asymmetric dihydroxylation and a doubly diastereoselective Mukaiyama aldol reaction to set up thestereogenic centers at C2, C3, C5, C7 and C8 with correct absolute configuration.</jats:p>
