E. Mizuguchi et K. Achiwa, OXALATE AS AN ACTIVATED ESTER GROUP IN LIPASE-CATALYZED ENANTIOSELECTIVE HYDROLYSIS - A VERSATILE APPROACH TO D-ALPHA-TOCOPHEROL, Tetrahedron : asymmetry, 4(11), 1993, pp. 2303-2306
The d-alpha-tocopherol was synthesized effectively by enzyme-catalyzed
enantioselective hydrolysis of dl-alpha-tocopherol oxalate. The enzym
es can recognize a stereogenic carbon atom remote from the reaction si
te.
