摘要

脱氢乙酸，通常缩写为DHA，其衍生物作为重要的中间体被广泛应用于有机合成，特别是杂环化合物的合成。8-芳基-7-烯-2,4,6-三酮(DHA-三酮，可由市售的DHA通过多步骤制备)与硫代氨基脲反应生成了一些新的2-甲基-5-苯基-7-硫氧基-6,7-二氢吡唑[1,5-c]嘧啶。

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

Dehydroacetic acid, commonly abbreviated as DHA, and its derivatives have been extensively used as important intermediates in organic synthesis particularly for the synthesis of heterocyclic compounds. The reaction of 8-aryloct-7-en-2,4,6-triones (DHA-triones, readily prepared from commercially available DHA by the use of a multistep procedure) with thiosemicarbazide led the formation of some new 2-methyl-5-styryl-7-thioxo-6,7-dihydropyrazolo[1,5-c] pyrimidines.
