Introduction of an oxygenated function at C-11 of the Erythrina alkaloid skeleton was obtained by treating erysovine with lead tetraacetate. Unfortunately simultaneous substitution of the C-3 OMe by -OAc has occurred and modifications as changing the reaction conditions and/or the phenolic compound to erysodine did not lead to successful results.
