Simultaneous Manipulation of Electric Double Layer and Zn (100) Deposition Enabled by Anions for Highly Stable Zn Anodes

Si Tang, Qingyi Wei, Baoquan Liu, Jinlin Yang et autres

Abstract Controlling the growth orientation of zinc (Zn) is an effective method of stabilizing Zn anodes. Although Zn (100) exhibits faster Zn electroplating/stripping kinetics than Zn (002), its high chemical reactivity results in susceptibility to water‐induced side reactions. Herein, a two‐pronged electrolyte …

Access to Piperazine-Fused Pyrrolocarbazoles Enabled by Acid-Catalyzed Stereoselective Hydroarylation of Ynamide–Indoles and Subsequent Diels–Alder Reactions/Aromatizations

Ze Zhou, Xiang Huang, Qingyi Wei, Yilin Wang et autres

Pyrrolocarbazole skeletons are well known to possess a variety of biological activities that might be therapeutically useful in the treatment of cancers. Herein, an acid-catalyzed stereoselective hydroarylation/Diels-Alder cycloaddition/aromatization of ynamide-indoles is described. We newly designed and synthesized a variety of piperazine-fused pyrrolocarbazole …

Rhodium(III)-Catalyzed Intramolecular Cyclization and Sequential Aromatization of Ynamides with Propargyl Esters: Access to 2,5-Dihydropyrroles and Pyrroles

Jin‐Ming Yang, Guang-Chao Feng, Xiang Huang, Yilin Wang et autres

Disclosed herein is a rhodium(III)-catalyzed intramolecular cyclization of ynamides with propargyl esters. A variety of highly functionalized 2,5-dihydropyrroles were obtained in moderate to good yields with high E / Z selectivities. Subsequent oxidation of the products gave valuable pyrrole derivatives. Additionally, scale-up …
