• A microbially-based approach for the synthesis of chiral secondary alcohols bearing the difluoromethyl or chlorodifluoromethyl group

  日期：1992.3

  A synthetic approach to both enantiomers of the secondary alcohols [Ph(CH2)n CH(OH)CXF2 (n = 0-2) C6H13(CH2)n CH(OH)CFX2 (n = 0 or 2) and CXF2CH(OH)CH2CO2Et [X = H or Cl], involving the stereoselective hydrolysis of ester derivatives, is described. The absolute configurations of these difluoromethylated or chlorodifluoromethylated molecules were determined.

  日期：1991.3

  A monoclonal antibody, elicited by a transition-state analogue for the hydrolysis of fluorinated esters, acted as an enzymelike catalyst for the preparation of chiral fluorinated compounds. The syntheses of (R)- or (S)-1-(fluoroalkyl)alkanols and an allylic alcohol possessing a trifluoromethyl group in high optical purity (> 98% enantiomeric excess (ee)) by antibody-derived reagents are described. The role of molecular recognition by antibody reagents and its importance to the preparation of optically pure materials is described. Significantly, it has been found that a fluoromethyl group on the stereogenic center or an acyloyl group enhanced the optical purity of the resultant products.
