α-hydroxy-1,2-diketone. The distinctive feature of the obtained photoproducts is ring–chain–ring tautomerism in solution. Based on X-ray analysis, the obtained photoproducts in the solid state exist in one isomeric form. Various types of derivatization of the synthesized compounds allow both forms of tautomers to be trapped.
开发了从含有
苯并咪唑片段的
异麦芽酚制备苯并[4,5]
咪唑并[1,2- a ]环戊[ e ]
吡啶衍生物的紫外线介导方法。建议的方法包括 ESI
PT 诱导的 3-hydroxypyran-4-one 核心收缩和不稳定的 α-hydroxy-1,2-diketone 的进一步分子内捕获。所得光产物的显着特征是溶液中的环-链-环互变异构现象。基于X射线分析,所获得的固态光产物以一种异构形式存在。合成化合物的各种类型的衍生化允许捕获两种形式的互变异构体。
