异苯并二氢吡喃并吡唑类化合物的合成
Sygnthesis of 3,4 - Dihydro - Isobenzopyrano[3,4 - c]pyrazoles
【摘要】 本文通过异苯并二氢吡喃酮-4的克莱森缩合反应得β-二酮衍生物,并由此合成出一系列标题化合物。所合成的新杂环化合物均经核磁共振光谱,红外光谱及无素分析证明其分子结构。
【Abstract】 Title compounds(3 -11) have been synthesized from β- diketone of 3,4 - dihydro-isobenzopyran which was prepared by Claisen condensation reaction. The composition and structure of all these compounds were characterized by elemental analysis, IR and 1H NMR.
