Lipase mediated preparation of differently protected homochiral 2-aryl- 2-fluoro-1,3-propanediols

Guanti, Giuseppe,Narisano, Enrica,Riva, Renata

, p. 1859 - 1862 (1998)

Lipase mediated asymmetric monohydrolysis of 2-aryl-2-fluoromalonic acid diesters or monoacetylation of 2-aryl-2-fluoro-1,3-propanediols affords chiral fiuorinated polyfunctionalized C3 synthons in excellent enantiomeric excess and acceptable chemical yields.
