Abstract
A catalysed O/C-carboxyl rearrangement generates the all-carbon stereogenic centre in phenyl 1,3-dimethyl-5-methoxy-2-oxoindoline-3-carboxylate (up to 57% ee). Crystallisation and removal of racemic crystals enhance the ee to 95%. The X-ray crystal structure of the cobalt metallocene-pyrrolidinopyridine nucleophilic catalyst employed is reported.
