• Lipase-catalyzed kinetic resolution of (RS)-hydroxy tellurides
  作者：Alcindo A. Dos Santos、Carlos E. Da Costa、Jefferson L. Princival、João V. Comasseto

  DOI：10.1016/j.tetasy.2006.07.024

  日期：2006.9

  The enzymatic resolution of racemic mixtures of hydroxy tellurides with a range of lipases has been investigated. Lipase-B from Candida antarctica (CALB) gave the best conversions, providing both enantiomers with high enantiomeric purity. A comparative study of the effect of solvent and substrate on the enzymatic kinetic resolution was performed. (c) 2006 Elsevier Ltd. All rights reserved.
• γ-Butyltelluro-2-butanol: a route to reactive 1,4-dianion intermediates

  gamma-Butyltelluro-2-butanol was reacted with 2 equiv of n-butyllithium. Both tellurium/lithium exchange and the proton abstraction reactions took place in a single step and the lithium dianion intermediate efficiently reacted with aldehydes and ketones, producing the corresponding diols.

• Functionalized organozincates and organocuprates derived from γ-hydroxytellurides in the preparation of 1,4-hydroxyketones

  日期：2009.11

  A C-O-dianionic zincate was generated by a Te/Li exchange reaction of an alkyltelluride, followed by Li/Zn transmetallation and reaction with methyllithium. The reaction between the enantiomerically pure (99% ee) (R)-dianionic zincate and benzoyl chloride led to 3-hydroxy-1-phenyl pentanone with total retention of the carbon configuration (99% ee). Similar results were obtained using the corresponding Lipshutz cyanocuprates. (C) 2009 Elsevier Ltd. All rights reserved.

  The components of the pheromone blend of Mayetiola destructor, Drosophila mulleri, and Contarinia pisi were synthesized in high enantiomeric excess (99% ee) from a common enantiopure dianion prepared from an enantiopure hydroxytelluride. (C) 2009 Elsevier Ltd. All rights reserved.
