Autor: Vladyslava Merkulova, Iryna Omelchenko, Olga V. Hordiyenko, Axelle Arrault, Volodymyr A. Tkachuk
Publikováno v: Tetrahedron Letters. 60:1959-1963
A new one-step, pseudo four-component approach for the synthesis of fully substituted pyridines via ring-opening of the cyclic acyl amidine of 3-amino-1H-isoindol-1-one and its aza-analogues during the reaction with malononitrile in the presence of s

A Green One-Pot Synthesis of vic-Amidino (Hetero)aromatic Acids from 1,2-Dinitriles
Autor: Iryna Omelchenko, Olga V. Hordiyenko, Volodymyr A. Tkachuk
Publikováno v: Synlett. 28:851-857
Phthalonitrile undergoes partial hydration in MeOH–H2O media in the presence of an equimolar amount of NaOH to afford 2-carbamimidoylbenzoic acid in good yield in one step. This and similar vic-amidino (hetero)aromatic acids also could be synthesiz
