Abstract

meso-Bis (acetoxymethyl)-1, 4, 5, 6, 7, 7-hexachlorobicyclo [2.2. 1] hepta-2, 5-diene and meso-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 ...
