VAN ES, Theodorus; STASKUN, Benjamin and KARUSO, Peter. The transposing of isomer yields in the methanolyses of N-substituted quinolinimides by triethylamine. S.Afr.j.chem. (Online) [online]. 2012, vol.65, pp. 53-61. ISSN 1996-840X.
The effect of triethylamine in transposing the respective yields of the two isomeric esters ensuing from the methanolysis of N-substituted quinolinimides is described and is rationalized with a mechanism.
Keywords : N-Substituted quinolinimides; methyl 2-carbamoyl-3-pyridinecarboxylates; methyl 3-carbamoyl-2-pyridinecarboxylates; benzenesulfonamide derivatives; triethylamine-induced rearrangements; reaction mechanisms.
