  Highly regioselective SN2′ reaction of β-fluoroallylic phosphates with organocopper reagents and its application to the synthesis of fluorine-containing carbocycles

  摘要：

  Treatment of beta-fluoroallyl phosphates with 2.2 equiv. of organocuprates, prepared readily from 2.2 equiv. each of CuCN and organometallics (organolithium reagents, Grignard reagents, and organozinc reagents), in THF at -40 to 0 degrees C for 0.25 to 24 h gave gamma-products in a highly regioselective manner. Thus obtained gamma-adducts were subjected to the ring-closing metathesis, the corresponding cyclic fluoroalkenes being afforded in good yields. (C) 2014 Elsevier B.V. All rights reserved.
