Abstract: | Simple methods for the synthesis of 3-aryl-6-methyl-2-pyrones and 3-aryl-5-carbalkoxy-6-methyl-2-pyrones by the reaction of ethyl -formylarylacetates with acetone and acetoacetic acid esters, respectively, are proposed. Some electrophilic substitution reactions of 6-methyl-3-phenyl-2-pyrone and 5-carbethoxy-6-methyl-3-phenyl-2-pyrone were studied.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 11, pp. 1477–1480, November, 1985. |
