Abstract
Abstract The synthesis and metallation of 4-methoxypicolin- and 2-methoxyisonicotin-anilides as a way of regiospecific transformation of picolinic and isonicotinic acids into 2, 3, 4-trisubstituted pyridines, is described. The resulted C 3 - alkylated derivatives underwent smooth acid - catalysed conversion into the corresponding pyridones.
