Highly enantioselective synthesis of long chain alkyl trifluoromethyl carbinols and β-thiotrifluoromethyl carbinols through lipases
摘要:
Among a variety of lipases tested, Candida antarctica lipase has been found to promote the enantioselective acylation of long chain alkyl trifluoromethyl carbinols 1a-4a and beta-thiotrifluoromethyl carbinols 5a-7a, producing both R and S enantiomeric alcohols in good to excellent chemical yield and enantioselectivity. In all cases the lipase preferentially acylates the S enantiomer, irrespective the presence or not of a sulfur atom in beta position to the hydroxyl group, When the reaction was carried out on the non-fluorinated substrates 1c-2c, the process occurred much faster and with higher e.e. of the less reacting enantiomer than when conducted on the fluorinated substrates.

The inhibition of insect juvenile hormone esterase by 3-octylthio-1,1,1-trifluoropropan-2-ol (K(i) = 9.5 x 10(-10)M) indicates that serine esterases may be unique from serine proteases.

gem-diol. These new compounds were evaluated for their inhibition of carboxylesterase activity in three different systems, rat liver microsomes, commercial porcine esterase, and juvenilehormoneesterase in cabbage looper (Trichoplusiani) hemolymph. The most potent inhibitor of rat liver carboxylesterase activity was 1,1,1-trifluoro-3-(decane-1-sulfonyl)-propan-2,2-diol, which inhibited 50% of the
