摘要:The present invention relates to compounds of formula I n nwherein R S denotes F or CF 3 , R a denotes H or C 1-4 -alkyl and Z denotes a leaving group or an optionally substituted or protected hydroxyl group, suitable as intermediates in the synthesis of indanyloxydihydrobenzofuranylacetic acids, which are GPR40 agonists, to a process for preparing these intermediates and to the process for preparing the GPR40 agonists making use of an asymmetric catalytic hydrogenation reaction in the presence of a transition metal catalyst and a chiral auxiliary.
