  Studies for the enantiocontrolled preparation of substituted tetrahydropyrans: applications for the synthesis of leucascandrolide A macrolactone

  摘要：

  Strategies for the stereocontrolled preparations of 2,6-cis- and 2,6-trans-substituted tetrahydropyrans have been devised. These studies have explored methodology for asymmetric induction in S-E' reactions using chiral 1,3,2-diazaborolidine controllers. Reactions with aldehydes at -78 degrees C yield nonracemic 1,5-diols for chemoselective internal backside displacements. This concept is developed as a flexible and reliable strategy in studies toward leucascandrolide A macrolactone 2 via the sequential applications of S-E' reactions leading to the C-1-C-9 aldehyde 14, and the bis-tetrahydropyran 59, respectively.

• Mild, versatile, and chemoselective indium(III) triflate-catalyzed deprotection of acetonides under microwave heating conditions
  作者：Kathryn C. Golden、Brian T. Gregg、John F. Quinn

  DOI：10.1016/j.tetlet.2010.05.116

  日期：2010.8

  A series of acetonides (both terminal and internal isopropylidene acetals) have been deprotected under catalytic, neutral conditions to give their corresponding 1,2-diols. The reactions utilize indium(III) triflate in the presence of water and an organic solvent with mild microwave heating. Terminal acetonides are chemoselectivley removed in the presence of internal acetonides; acid labile functional groups remain intact under these conditions, thereby greatly enhancing the scope of the reaction substrates that can be utilized with this approach.

• A site-selective and stereospecific cascade Suzuki–Miyaura annulation of alkyl 1,2-bisboronic esters and 2,2′-dihalo 1,1′-biaryls

  日期：——

  A cascade Suzuki–Miyaura cross-coupling giving rise to 9,10-dihydrophenanthrenes has been developed. Using biaryls with unsymmetrical substitution-pattern full site-selectivity was observed. Furthermore, this cross-coupling of an alkyl 1,2-bisboronic pinacol ester proceeds through the challenging coupling of a secondary boronate with complete stereoretention.
