  摘要：

  A general and enantiocontrolled synthetic route to 2-arylpropionic acids, represented by non-steroidal anti-inflammatory drugs S-naproxen 1a and S-ibuprofen 1b, has been developed by employing the lipase-mediated asymmetric acetylation of prochiral 2-aryl-1,3-propanediol 3, which has been derived via a Heck reaction, as the key step.

  A hydrolase producing strain Trichosporon beigelli esterase (TBE) isolated from local cottage cheese in its native form has displayed versatility and high efficacy in the kinetic resolution of a wide range of economically important substrates, which include racemic secondary alcohols, such as 1-(6-methoxy-2-naphtliyl)ethanol (E similar to 316), 1-(3,4-methylenedioxyphenyl)ethanol and pentanol (E similar to 180 and 156 resp.), and alkyl esters of carboxylic acids such as ibuprofen (E similar to 340), 2-(benzylthio)propanoic acid (E similar to 1000). In other substrates such as in the primary alcohol 2-(6-methoxy-2-naphthyl)propan-1-ol and carboxylic acids such as 2-(5-bromo-6-methoxy-2-naphthyl)propanoic acid, 2-(2-naphthyloxy)propanoic acid, and substituted 2-thiopropanoic acids, it displayed moderate to low selectivity. Commercial lipases such as CCL, PPL, and PSL were also used in the resolution of the substrates for comparative studies. (c) 2005 Elsevier Ltd. All rights reserved.
