摘要:
An easy method to prepare novel 4-alkoxy-, 4-alkylthio- or 4-aryloxy-5-methyl-2-[1-(hydroxy-methyl)-2-(1-naphthyl)-ethyl (or -ethenyl)]pyridine derivatives having reversible inhibitory activity against H+/K+ ATPase is described. Use of a methylsulfinyl- or methylsulfonyl group as a leaving group makes it possible to effectively introduce Various alkoxy or alkylthio groups into the 4-position of the pyridine ring at the final stages of synthesis. Biological profiles of the prepared compounds are briefly mentioned. (C) 1997 Elsevier Science Ltd.
