Abstract

meso-Bis(acetoxymethyl)-1,4,5,6,7,7-hexachlorobicyclo[2.2.1]hepta-2,5-diene and i)ieso-bis(hydroxymethyl)-1,4,5,6,7,7-hexachlorobicyclo[2.2.1]hepta-2,5-diene were transformed into chiral monoesters with 65-92% ee via enzymatic desymmetrization using various lipases. The absolute configuration was determined by transforming 2-acetoxymethyl-3-hydroxymethyl-1,4,5,6,7,7-hexachlorobicyclo[2.2.1]hepta-2,5-diene into the 2-acetoxymethyl-3-hydi-oxymethylbicyclo[2.2.1]hepta-2,5-diene of known absolute configuration.
