Synthesis of substituted pyridines catalyzed by gold complexes
Matouš, Petr ; Pour, Milan (advisor) ; Klimešová, Věra (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Inorganic and Organic Chemistry Candidate: Petr Matouš Supervisor: Prof. RNDr. Milan Pour, Ph.D. Title of thesis: Synthesis of substituted pyridines catalyzed by gold complexes This work is focused on the synthesis of 3,4-disubstituted pyridine derivatives. MBS-protected propargylamine reacts with methyl propiolate to form 1,5-enyne that undergoes Sonogashira coupling with aryl iodides. Substituted enyne undergoes cyclization to tetrahydropyridine in the presence of tris(2-furanyl)phosphinegold(I)chloride. Deprotection leads to the preparation of substituted pyridines, which could serve as intermediates in organic synthesis or as potential biologically active substances. Keywords: gold catalysis, enyne cyclization, pyridine derivatives
