摘要 |
(57): In accordance with the present invention there are provided methods for producing enantio merically pure .alpha.-sustituted carboxylic acids, such as, for example, .alpha.-amino acids and .alpha.- hydroxy acids, said method comprising combining an aldehyde or ketone with a cyanide and ammonia or an ammonium salt or an amine, in the presence of a nitrilase or a polypepdde having nitrilase activity which stereoselectively hydrolyzes the amino nitrile or cynohydtin intermediate under conditions sufficient to produce the carboxylic acid. |
