Dynamic kinetic resolution of 2,3-dihydrobenzo[be]furans: Chemoenzymatic synthesis of analgesic agent BRL 37959

An efficient asymmetric synthesis of (S)-2,3-dihydrobenzo[be]furan-3- carboxylic acid (8 ) and (S)-5-chloro-2,3-dihydrobenzo[be]furan-3-carboxylic acid (8a b) was established. Key to the success was the highly stereoselective enzymatic kinetic resolution
