Kim, Minjae; Park, Bohyun; Shin, Minkyeong; Kim, Suyeon; Kim, Junghoon; Baik, Mu-Hyun; Cho, Seung Hwan published their research in Journal of the American Chemical Society in 2021. The article was titled 《Copper-Catalyzed Enantiotopic-Group-Selective Allylation of gem-Diborylalkanes》.SDS of cas: 2635-13-4 The article contains the following contents:
The authors report a Cu-catalyzed enantiotopic-group-selective allylation of gem-diborylalkanes with allyl bromides. The combination of Cu(I) bromide and H8-BINOL derived phosphoramidite ligand proved to be the most effective catalytic system to provide various enantioenriched homoallylic boronate esters, containing a B-substituted stereogenic center that is solely derived from gem-diborylalkanes, in good yields with high enantiomeric ratios under mild conditions. Exptl. and theor. studies were conducted to elucidate the reaction mechanism, revealing how the enatiotopic-group-selective transmetalation of gem-diborylalkanes with chiral Cu complex occurs to generate chiral α-borylalkyl-Cu species for the 1st time. Addnl. synthetic applications to the synthesis of various chiral building blocks are also included. In the experiment, the researchers used 5-Bromobenzo[d][1,3]dioxole(cas: 2635-13-4SDS of cas: 2635-13-4)
Furthermore, the coupling of 5-Bromobenzo[d][1,3]dioxole(cas: 2635-13-4) with β-methallyl alcohol was catalyzed by Pd(OAc)2 in combination with P(t-Bu)3.SDS of cas: 2635-13-4
