provides C-, N-, O- or S-substituents in the benzoheterocycles obtained. The photochemical step is a metal-, acid-, and oxidant-free reaction, which requires non-inert conditions, and can be easily monitored by NMR spectroscopy. Applicability of the proposed strategy was tested in the synthesis of a wide range of substituted carbazoles and benzo[b]thiophenes as well as on a gram-scale benzannulation of 3-indoleacetic
首次提出了通过1,2-二杂芳烃的光环化制备芳香族杂环的一般方法。该策略包括两个步骤,即从广泛可用的3-杂戊酸和2-溴-1-杂蒽酮中组装二甲基蒽的模块,以及后续的制备性光重排(使用365 nm的紫外灯作为光源)。这种方法对于各种杂环的环化都是有效的,并提供C-,N-,O-或S获得的苯并杂环中的-取代基。光化学步骤是无金属,无酸和无氧化剂的反应,这需要非惰性条件,并且可以通过NMR光谱轻松监控。在广泛取代的咔唑和苯并[ b ]噻吩的合成以及克级的3-吲哚乙酸的苯环上,测试了所提出策略的适用性。我们的研究揭示了如何克服成功地对二芳硫醚进行光重排的两个显着障碍:与光生单重态氧相关的不良反应以及所需产物的不稳定性。第一个问题通过添加DABCO成功解决,同时现场开发 捕获不稳定光产物的烷基化方案使我们能够克服第二个问题。

Photochemical rearrangement of diarylethenes: synthesis of functionalized phenanthrenes

photocyclization of diarylethenes (DAE) under UV irradiation is proposed. The reaction proceeds through 6π-electrocyclization with the formation of a cyclic (closed) intermediate that undergoes a rearrangement affording unsymmetrical phenanthrenes in good yields. However, in contrast to benzene derivatives, the photocyclization of naphthalene diarylethenes proceeds more slowly, which is confirmed by DFT

DFT calculations and X-ray crystallography. All compounds undergo irreversible photochemicaltransformations under irradiation with ultraviolet light, proceeding through the photocyclization stage. It has been found that only some normal (thiophene, imidazole and pyrazole derivatives) and inverse type (oxazole derivative) diarylethenes form colored photoinduced isomers under UV.
