Abstract
A new synthesis of (<2(R)under bar>,<3(S)under bar>)[4-H-2(3)] valine was developed, and used to synthesise (<2(R)under bar>) [2'-H-2(3)]-pe nicillin N via a chemico-enzymatic synthesis. This labelled penicillin was then used to demonstrate the stereospecific ring expansion of pen icillin N to deacetoxycephalosporin C by deacetoxycephalosporin C synt hase from Streptomyces clavuligerus.
