Synthesis of N-Derivatives of Cytisine, Anabasine, and Salsoline Alkaloids with Pharmacophore 3-Aminopyridine-2(1H)-one and 5-Methyl-7-phenyloxazole[5,4-b]pyridine Cycles

Resumo

The reaction of nucleophilic substitution of 2-chloro-N-(6-methyl-2-oxo-4-phenyl-1,2-dihydropyridin-3-yl)acetamide and 2-(chloromethyl)-5-methyl-7-phenyloxazolo[5,4-b]pyridine with cytisine, anabasine, and salsoline alkaloids has afforded the corresponding derivatives. Structure of the obtained compounds has been confirmed by means of ¹H and ¹³C NMR spectroscopy.
