Copper-free defluorinative alkylation of allylic difluorides through Lewis acid-mediated C–F bond activation
摘要:
The reactions of difluorohomoallyl alcohols with trialkylaluminiums smoothly proceeded in CH2Cl2 at room temperature to give (Z)-fluoro-olefin products in excellent yields. On the basis of this chemistry, fluoro-olefinic dipeptide isostere of norvalinyl glycine was synthesized in stereoselective manner. (C) 2011 Elsevier Ltd. All rights reserved.
