  A Two-Directional Approach to a (−)-Dictyostatin C11−C23 Segment:  Development of a Highly Diastereoselective, Kinetically-Controlled Meerwein−Ponndorf−Verley Reduction

  摘要：

  A three-step synthesis of a precursor to the C11-C23 segment of (-)-dictyostatin is described. The sequence features a sonication-assisted, enantioselective double hetero Diels-Alder (HDA) reaction catalyzed by Jacobsen's Cr(III) Schiff base catalyst, followed by a novel, highly diastereoselective Meerwein-Ponndorf-Verley (MPV) reduction of the hydropyranone subunits under kinetic control to yield the bis(axial alcohol) 4. Generalized studies of both the HDA and MPV methodologies are also described.

  Highly Enantio- and Diastereoselective Hetero-Diels-Alder Reactions Catalyzed by New Chiral Tridentate Chromium(III) Catalysts

  摘要：

  Even moderately nucleophilic dienes react with simple aldehydes in the presence of a new Cr(III) catalyst in a hetero-Diels-Alder reaction [Eq. (1)]. Tetrahydropyranyl products with up to three stereogenic centers are generated in near-perfect diastereoselectivities and with greater than 90 % ee (99 % ee for the example shown). TBAF=tetrabutylammonium fluoride; TBS=tert-butyldimethylsilyl; TES=triethylsilyl.
