  Substrate-Directed Diastereoselective Hydroformylation: Key Step for the Assembly of Polypropionate Subunits

  摘要：

  Stereoselective hydroformylation of methallylic alcohols of types 3 and 4, that employed the substrate-bound catalyst-directing ortho-diphenyl-phosphanylbenzoyl (o-DPPB) group, was used as a key step for the construction of bifunctionalized stereotriads, which ale central building blocks of polyketide natural products. The required diastereomerically pure syn- and anti- starting methallylic alcohol systems 3 and 4 were obtained either by Cram-selective carbonyl reduction, Frater alkylation, or by chelation-controlled carbonyl reduction. Enantiomerically pure stereotriad building blocks were derived from a combination of an Evans aldol addition and subsequent o-DPPB-directed stereoselective hydroformylation (-->24). A crystal structure analysis for steretriad building block 24 confirmed the relative and absolute configuration of the stereogenic centers. Additionally, it provided evidence for a previously postulated preferred conformation of the catalyst-directing o-DPPB group as well as of the polyketide main chain.

  Killing two birds with one stone. The ortho-diphenylphosphanylbenzoyl group (o-DPPB) acts as a catalyst-directing group in stereoselective Rh-catalyzed hydroformylation and as a reagent-directing group in stereoselective 1,4-addition of Gilman cuprates to acyclic enoates (see picture on the right; the o-DPPB group is represented by a sphere, D=donor). These two reactions could be efficiently used as
