functionalized indanones that structurally resemble biologically active pterosines. Nanosecond laser flash photolysis and quantum-chemical calculations based on density functional theory provided evidence that this photochemical transformation proceeds primarily via a photoenolization mechanism. Our study revealed considerable complexity of the mechanism and that structural modifications can significantly
辐照2,5-二甲基苯甲酰肟酮可形成相对高效和高产率的β-羟基官能化的茚满酮,其结构上类似于生物活性翼龙素。纳秒激光闪光光解和基于密度泛函理论的量子化学计算提供了证据,表明这种光化学转变主要是通过光致化机理进行的。我们的研究揭示了该机理的相当复杂性,并且结构修饰可以显着改变反应途径并产生不同的产物。研究了这种光化学转化用于合成某些药学上重要的化合物的范围。
