  Tandem nucleophilic addition-intramolecular oxa-Michael reaction: Novel synthetic route to trifluoromethylated phthalans

  摘要：

  The reaction of ortho-formyl cinnamates, ortho-formyl cinnamonitrile and ortho-formyl alpha-benzalketones with trifluoromethyltrimethylsilane in the presence of cesium fluoride results in the formation of trifluoromethylated phthalans in good yields. This approach provides a novel and facile access to the biologically important fluorine-containing phthalans. (C) 2013 Elsevier B.V. All rights reserved.
