Fund Project:

Poly-L-valine was modified on graphite to produce polymer modified graphite electrode(Ce/PLV) on which phenylglyoxylic acid(PGA) was reduced to S(+)-mandelic acid(SMA).By using Ce/PLV,the optical yield(o.y.) of SMA and conversion percent of PGA were measured as functions of various factors.The highest o.y. obtained under optimized conditions was 63.8%.A possible stereochemical model of asymmetric reduction of PGA was proposed.
