异色满酮-4及其衍生物的合成 Ⅹ.异色满并嘧啶并唑类杂环化合物的合成

Synthesis of Isochroman4one and Its Derivatives . Synthesis of Isochromanopyrimidinoazoles

通过异色满酮－４的克莱森缩合反应得到其α，β－不饱和衍生物，后者分别与３，５－二氨基－４－苯偶氮吡唑、３－氨基－１，２，４－三唑和２－氨基－苯并咪唑缩合，得到相应的四环和五环系列标题物。所合成的新化合物的结构均经元素分析。

The tittle compounds have been synthesized by means of condensation reaction of ,unsturated isochroman4one with 3amino1,2,4triazole, 3,5diamino4( p substitutedphenyl)pyrazole or 2aminobenzimidazole. The structures of these compounds were established by elemental analysis,IR and 1HNMR.
