英文摘要: A catalytic diastereo- and enantiocontrolled preparation of cis-beta-fluorocyclopropane carboxylates through the Rh-catalyzed cyclopropanation of alkenyl fluorides with diazoarylacetates has been realized. Rh-2(S-DOSP)(4) and benzyl diazoarylacetates were found to be beneficial to the cyclopropanation with high diastereoselectivity. Thirteen cis-beta-fluorocyclopropane carboxylates were prepared in hexane at 0 degrees C with good to excellent yields. The enantiomeric excess was up to 97%, and the diastereomer ratio was up to 95:5. (C) 2015 Elsevier Ltd. All rights reserved.
