    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.

  • Synthesis and Conformational Analysis of Geodiamolide Analogues

    ω-hydroxy and ω-amino acid derivatives 13 and 21, the two closely related geodiamolide analogs 32 and 35, respectively, were prepared. Compared to the natural cyclodepsipeptide geodiamolide (1), the macrocycles 32 and 35 have a smaller ring size (17- vs. 18-membered). Conformational analysis by ROESY spectroscopy and molecular dynamics simulation revealed that the reduced ring size causes the polypropionate

    Pre-schisanartanin C belongs to the family of Schisandra nortriterpenoids with potent antihepatitis, antitumor, and anti-HIV activities. This paper presents the enantioselective total synthesis of pre-schisanartanin C (1). An important step in the total synthesis of 1 is gold-catalyzed intramolecular cyclopropanation of an 1,8-enyne substrates bearing a secondary ester group at the propargylic position

    achieved. The basis of this result was a careful substrate design making use of a syn-pentane interaction as the decisive stereochemical control element. Confirmation of this working hypothesis came from conformational analysis studies on alkenic substrate 16 employing 2D NOESY experiments in solution and MACROMODEL/MM3 calculations. This stereoselective, transition metal-catalyzed, C-C bond-forming
