So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Bao, Ming; Lu, Wei; Su, Han; Qiu, Lihua; Xu, Xinfang researched the compound: 1-(Bromomethyl)-4-ethylbenzene( cas:57825-30-6 ).Electric Literature of C9H11Br.They published the article 《A convergent formal [4+2] cycloaddition of 1,6-diynes and benzyl azides: construction of spiro-polyheterocycles》 about this compound( cas:57825-30-6 ) in Organic & Biomolecular Chemistry. Keywords: spirotetrahydroquinoline preparation diastereoselective; diyne benzyl azide cycloaddition gold Bronsted acid catalyst. We’ll tell you more about this compound (cas:57825-30-6).
A convergent formal [4+2] cycloaddition reaction for the construction of structurally appealing spiro-tetrahydroquinolines has been developed, in which, a one-pot reaction is established for the in situ generation of two reagents, a cyclic alkyne and an N-aryliminium ion, from the corresponding precursors in the presence of an Au-catalyst and Bronsted acid, resp.
When you point to this article, it is believed that you are also very interested in this compound(57825-30-6)Electric Literature of C9H11Br and due to space limitations, I can only present the most important information.
