Xia, Biao; Chen, Wenjun; Zhao, Qiongli; Yu, Wenquan; Chang, Junbiao published the artcile< Synthesis of Functionalized Imidazolium Salts via Iodine-Mediated Annulations of Enamines>, SDS of cas: 94-02-0, the main research area is imidazolium salt preparation; enamine preparation annulation iodine.
A novel annulation reaction of two enamine mols. with iodine under basic conditions to form 4-functionalized imidazolium salts has been established. In this reaction, iodine acts as both an iodinating reagent and a Lewis acid catalyst. Features of this synthetic method include facilitative preparation of substrates, no use of transition metals, mild reaction conditions, simplicity of operation, and gram scale synthesis.
Organic Letters published new progress about Cyclization. 94-02-0 belongs to class esters-buliding-blocks, and the molecular formula is C11H12O3, SDS of cas: 94-02-0.
