Abstract

Abstract Commercial dehydroacetic acid was converted into 4-hydroxy-6-methylpyridin-2 (1H)-one (3), which was then condensed with several aliphatic aldehydes to produce seven new title compounds in variable yields (35–92%). Reaction of 3 with α, β-unsaturated aldehydes resulted in the formation of condensed pyran derivatives 4g'and 4h'. A mechanism is proposed to explain the formation of such compounds. The effects of all ...
