摘要

封面内页的图片说明了吡唑并[1,2-a]吡唑酮向三维丰富杂环系统的新颖波长依赖性转化。带手电筒的机器人代表了如何通过简单地调节照射波长轻松获得两种不同的产物，通过扩环生成 1,2-二氮杂环，或通过连续的 4π 电环化生成三环产物。这些转化具有高度的立体选择性，不需要光催化剂或添加剂，而且很容易扩大规模。更多详情，请参阅 I. Kulašić、B. Štefane 及其合作者的研究文章（I. Kulašić、N. Petek、H. Brodnik、U. Grošelj、J. Svete、B. Štefane，Adv. Synth.Catal.2024, 366, XXXX-XXXX; DOI: 10.1002/adsc.202400684)

Photocatalyst-Free Wavelength-Dependant Sequential Ring Transformations of Pyrazolo[1,2-a]pyrazolones.

The inside cover picture illustrates novel wavelength-dependent transformations of pyrazolo[1,2-a]pyrazolones into 3D-rich heterocyclic systems. The robot with flashlights represents how two distinct products can be easily obtained by simply adjusting the irradiation wavelength, leading to either 1,2-diazepines through ring expansion or tricyclic product via consecutive 4π-electrocyclization. These transformations are highly stereoselective, do not require photocatalysts or additives, and can be easily scaled up. For more details, see the Research Article by I. Kulašić, B. Štefane and co-workers (I. Kulašić, N. Petek, H. Brodnik, U. Grošelj, J. Svete, B. Štefane, Adv. Synth. Catal. 2024, 366, XXXX–XXXX; DOI: 10.1002/adsc.202400684)

期刊介绍： Advanced Synthesis & Catalysis (ASC) is the leading primary journal in organic, organometallic, and applied chemistry. The high impact of ASC can be attributed to the unique focus of the journal, which publishes exciting new results from academic and industrial labs on efficient, practical, and environmentally friendly organic synthesis. While homogeneous, heterogeneous, organic, and enzyme catalysis are key technologies to achieve green synthesis, significant contributions to the same goal by synthesis design, reaction techniques, flow chemistry, and continuous processing, multiphase catalysis, green solvents, catalyst immobilization, and recycling, separation science, and process development are also featured in ASC. The Aims and Scope can be found in the Notice to Authors or on the first page of the table of contents in every issue.
