A stereoselective synthesis of L-carbidopa in seven steps and 50% overall yield from commercial compounds is described. The key step involves a highly enantioselective α-amination reaction of an acyclic β-ketoester with di-tert-butyl azodicarboxylate induced by europium and (R,R)-diphenyl-pybox.

Parkinson's disease patients treated chronically with levodopa often develop fluctuations in motor response. Motor fluctuations can be attributed in part to oscillating plasma levodopa concentrations. A controlled-release formulation containing 200 mg of levodopa and 50 mg of carbidopa provides superior
