  Enantioselective Synthesis of 10-epi-Anamarine via an Iterative Dihydroxylation Sequence

  摘要：

  The enantioselective syntheses of 10-epi-anamarine and 5,10-epi,epi-anamarine have been achieved in 13 to 14 steps. The route relies upon an enantio- and regioselective Sharpless dihydroxylation of either dienoates or trienoates to establish the C-8 to C-11 stereochemistry. A diastereoselective Leighton allylation established the desired C-5 stereochemistry. The route also relies upon a ring-closing metathesis to establish the alpha,beta-unsaturated lactones.

  De Novo Enantioselective Syntheses of Galacto-Sugars and Deoxy Sugars via the Iterative Dihydroxylation of Dienoate

  摘要：

  [GRAPHICS]An efficient route to various sugar lactones has been developed. Key to the overall transformation is the sequential osmium-catalyzed dihydroxylation of 2,4-dienoates. The simplest (one-step/racemic) example of this reaction occurs when the dihydroxylation is performed with aqueous NMO in MeOH. When the first dihydroxylation is performed using the AD-mix procedure, an enantioselective variant results. When a matched AD-mix procedure is used for the second dihydroxylation, an exceedingly diastereo- and enantioselective synthesis of galacto-1,4-lactone results.

  A concise and stereoselective route for the synthesis of the carbohydrate moiety of the antifungal agent Sch 38516 is described. The synthesis scheme includes a dipolar cycloaddition, which is rendered diastereoselective through the use of a readily available and easily removable chiral auxiliary.

• Synthesis of β,γ-disubstituted-γ-lactones through a Johnson–Claisen rearrangement: a short route to xylobovide, nor-canadensolide, canadensolide, sporothriolide and santolinolide

  日期：2009.12

  The Johnson-Claisen rearrangement of allyl alcohols with chiral vicinal diol functionality was employed to access chiral beta,gamma-disubstituted-gamma-lactones in high enantio- and diastereoselectivity. These were efficiently converted into nor-canadensolide, the advanced gamma-(lactone-lactol) intermediate for xylobovide, canadensolide and sporothriolide and the lactone moiety of the santolinolides.
