合成路线1
该中间体在本合成路线中的序号：(V)Oxcarbazepine (I) was reduced with NaBH4 to afford the racemic alcohol (IIa-b). Esterification with (-)-menthoxyacetic acid chloride (III) in the presence of dimethylaminopyridine provided the diastereomeric mixture of esters (IV) and (V), from which the desired isomer (V) was isolated by fractional crystallization from CH2Cl2/EtOAc. Basic hydrolysis of (V) then provided pure (R)-alcohol (VI). Finally, esterification of (VI) with acetyl chloride led to the title acetate ester.
