The novel stereoselective and regioselective alkali metal borohydride reduction of 2,5-diketogluconic acid, alkyl esters or salts thereof to form 2-ketogulonic acid together with lesser amounts of 2-ketogluconic acid is disclosed. The 2-ketogulonic acid is readily converted to ascorbic acid.
本文介绍了一种新型的立体选择性和区域选择性碱
