Scheme 8. Pd–catalyzed cross–coupling of electron–deficient fluoro–aromatics with N–tosylhydrazones and the reaction pathway. In Suzuki-type cross-coupling reactions, direct cross-coupling of organometallic reagents with fluoro-aromatics is relatively rare. In 2005, Dankwardt et al. carried out...

The Suzuki cross-coupling reaction of 3-acetylphenylboronic acid with 2-chloro-5-fluoropyrimidine afforded compound 9. The reaction of compound 9 with chiral alcohols 4 or 5 with sodium hydride yielded compounds 10a-b. Asymmetric hydrogen transfer of compounds 10a-b with the same procedure, using...
Using biomass-derived solvents in various organic reactions is challenging for the fine chemicals industry. We herein report a Pd/C catalyzed Suzuki–Miyaura reaction in water extract of suaeda salsa (WES) without using external phosphine ligand, base, and organic solvent. The cross-coupling reaction...
such as HIV and HBV, showed no cross-reactivity. Our results are consistent with those of a study that reported no cross-reaction of the CRISPR–Cas12a assay to detect HBV [22]. Therefore, the coupling of the RT-LAMP with the CRISPR–Cas12 assay offered a highly specific and robust dete...
