最近， 王洪玉课题组成功地开发了一种在可见光介导下，通过底物光敏策略和极性反转策略来合成 3,3-二取代氧化吲哚的无光催化剂的方法。初步的机理研究表明，靛红酮亚胺衍生物可以被可见光直接激发生成强氧化态，从而促进后续与Hantzsch酯的单电子转移（SET）过程，生成相应的α-氨基自由基中间体。α-氨基自由基中间体促进了随后的Giese ...

研究者证明了物理系统中可以存在与费米子或玻色子等价的非平凡准统计量。这些新类型的相同粒子遵循广义不相容原理，导致与任何自由费米子和玻色子系统不同的奇异自由粒子热力学。

Natural products are small molecules produced naturally by any organism including primary and secondary metabolites. They include very small molecules, such as urea, and complex structures, such ...

In this study, we used microscopic, spectroscopic, and molecular analysis to characterize endolithic colonization in gypsum (selenites and white crystalline gypsum) from several sites in Sicily. Our ...

This study is important, with the potential to greatly impact future research on the evolution of chemical defense mechanisms in animals. The authors present compelling evidence for the presence of ...

Chemical structures of antimalarial sesquiterpene lactones: artemisinin (7), artesunate (8), artemether (9), arteether (10) and dihydroartemisinin (11). The discovery of new antimalarial compounds is, ...
