Synthesis of 3,5,7-triketo acids and esters and their cyclizations to resorcinol and phloroglucinol derivatives. Models of biosynthesis of phenolic compounds
8-Aryloct-7-en-2,4,6-triones as Useful Precursors for the Regioselective Synthesis of Some New 2-Methyl-5-styryl-7-thioxo-6,7-dihydropyrazolo[1,5-c]pyrimidines
摘要:
脱氢乙酸(通常缩写为 DHA)及其衍生物已被广泛用作有机合成的重要中间体,尤其是用于合成杂环化合物。8-aryloct-7-en-2,4,6-triiones (DHA-triiones,通过使用多步骤程序很容易从市售 DHA 中制备)与硫代氨基甲酰反应生成了一些新的 2-甲基-5-苯乙烯基-7-硫酮-6,7-二氢吡唑并[1,5-c]嘧啶。
