| Abstract | ||
| Four isomers of pyridine lactone were synthesized by reduction of readily available pyridine dicarboximides to the corresponding amides by sodium borohydride in acidic ethanolic solution to give the two isomers of hydroxyl methyl pyridine amide. Lactonisation of the later was best achieved using either hydrochloric acid or heating in toluene. The structure of all compounds were identified by the available physical, chemical and spectroscopic methods. | ||
