Synthesis by benzilic acid rearrangement of the 2-oxo-3-pyrroline dimeric alkaloid of Mercurialis leiocarpa

Abstract The 2-oxo-3-pyrroline dimer, 3,3′-bis(1,1′-dimethyl-2,2′-dioxo-4,4′-dimethoxy-5,5′-dihydroxy-5,5′-dimethoxycarbonyl-3-pyrroline), present in Mercurialis leiocarpa has been synthesized.
