The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate( cas:36620-11-8 ) is researched.Application of 36620-11-8.Yao, Lin; Ma, Haixia; Nie, Zhuang; Nie, Huifang; Zhang, Dongxu; Wei, Zhao; Shen, Zhanhong; Chen, Weiping; Jiang, Ru; Zhang, Shengyong published the article 《A practical strategy to access chiral α-aryloxy carboxylic acids through ion-pairing directed asymmetric hydrogenation》 about this compound( cas:36620-11-8 ) in Organic Chemistry Frontiers. Keywords: alpha aryloxy carboxylic acid enantioselective preparation; unsaturated carboxylic acid hydrogenation Chenphos rhodium catalyst; amide alpha aryloxy preparation. Let’s learn more about this compound (cas:36620-11-8).
A series of optically active α-aryloxy carboxylic acids I [R1 = n-Bu, 2-furyl, 4-F3CC6H4, etc.; R2 = H, 4-ClC6H4, 4-PhC6H4, etc.] was obtained via Chenphos/Rh catalyzed highly efficient asym. hydrogenation. The proposed ion-pairing interaction between ligand and substrate played a vital role in achieving high enantioselectivity.
