Gopalaiah, Kovuru published the artcileSynthesis of Krohnke pyridines through iron-catalyzed oxidative condensation/double alkynylation/amination cascade strategy, HPLC of Formula: 6850-57-3, the publication is Tetrahedron (2021), 132429, database is CAplus.
An efficient protocol for the synthesis of sym. and unsym. 2,4,6-trisubstituted pyridines via oxidative cascade annulation of arylacetylenes with benzylamines was developed. The reaction proceeded smoothly by utilizing iron(II) triflate as a catalyst and mol. oxygen as an oxidant with broad substrate scope. Mechanistic studies revealed that the reaction may experience an oxidative condensation followed by double alkynylation and amination process.
