Boosting the Enantioselectivity of Conjugate Borylation of α,β-Disubstituted Cyclobutenones with Monooxides of Chiral C2-Symmetric Bis(phosphine) Ligands was written by Cui, Ming;Zhao, Zhi-Yuan;Oestreich, Martin. And the article was included in Chemistry – A European Journal in 2022.Related Products of 67237-53-0 This article mentions the following:
Chiral bis(phosphine) monooxides (BPMOs) derived from C2-sym. bis(phosphines) have been found to induce superior levels of enantioselection in copper-catalyzed conjugate borylation of α,β-disubstituted cyclobutenones. More precisely, enantiomeric excesses as well as chem. yields are exceedingly high with (R,R)-Bozphos as the chiral ligand while these values are low with parent (R,R)-Me-Duphos. A similar yet less pronounced effect was seen in the corresponding 1,6-addition to para-quinone methides. In the experiment, the researchers used many compounds, for example, 3-Ethynylthiophene (cas: 67237-53-0Related Products of 67237-53-0).
3-Ethynylthiophene (cas: 67237-53-0) belongs to benzothiophene derivatives. Functionalized benzothiophenes are important constructs found in molecules with wide ranging biological activity and in organic materials. It is also used in the manufacturing of dyes such as thioindigo.Related Products of 67237-53-0
