  Asymmetric hydroboration and Matteson homologation for the preparation of fluorinated α-phenethanols

  摘要：

  The asymmetric catalytic hydroboration-oxidation of ring-fluorinated styrenes (F-PhCH=CH2) was achieved with catecholborane along with a combination of [Rh(COD)(2)]+BF4- and (R)-BINAP providing 81-96% enantioselectivities for the product alcohols for ortho-unhindered styrenes. A deleterious effect of a 2,6-disubstitution on the enantioselectivity of the product alcohol was observed. 2-Trifluoromethylstyrene also provides only 53% ee, probably due to the steric bulk of the CF3 group at the ortho-position of styrene. Asymmetric homologation of fluorophenylmetals (magnesium bromide or lithium) with pinanediol alpha-chloroethylboronate, followed by oxidation readily furnished the desired 1-(2,6-difluorophenyl)- and 1-(perfluorophenyl)ethanols in 94-95% ee.
