  The synthesis of 3,6-dihydropyrans and 4,5-epoxytetrahydropyrans starting from enantiomerically pure β-hydroxy aldehyde (prepared by an organocatalytic aldol reaction) is described. The key step is a tandem sequence, which consists of a base-promoted conjugative addition to a vinyl onium salt, followed by either an intramolecular Wittig process to provide 3,6-dihydropyran derivatives or an intramolecular

• Direct, pyrrolidine sulfonamide promoted enantioselective aldol reactions of α,α-dialkyl aldehydes: synthesis of quaternary carbon-containing β-hydroxy carbonyl compounds
  作者：Wei Wang、Hao Li、Jian Wang

  日期：2005.7

  A procedure has been developed for direct, asymmetric aldol reactions of alpha,alpha-dialkyl aldehydes with aromatic aldehydes, which produces quaternary carbon-containing beta-hydroxy carbonyl compounds. The processes, promoted by the organocatalyst (S) pyrrolidine sulfonamide, take place in high yields with exceptionally high levels of enantioselectivities. (c) 2005 Elsevier Ltd.
