Also, the biaryl
core of the ligand can be simplified to formally chiral 6, 2'-dimethylbiphenyl, and eventually 2-bromotoluene and 2-tolylboronic acid can be selected as the simplest substrates of the enantioselective cross-coupling reaction (Scheme 3).
They cover asymmetric C-H bond insertion reactions, symmetric cross-dehydrogenative coupling reactions, asymmetric oxidative biaryl
coupling reactions, asymmetric [1,5]-hydride transfer reactions, asymmetric functionalization of C-H bonds via a transient carbon-metal species, asymmetric Friedel-Crafts alkylation reactions, N-heterocyclic carbene-catalyzed asymmetric functionalization of aldehyde C-H bonds, asymmetric hydroacylation reactions, and asymmetric hydrovinylation reactions.
structures are extensively found in many of the natural products including terpenes, alkaloids, flavonoids, lignan, and tannins etc [1, 2].
The bromide compound 7 and 7a and the aldehyde 10 were coupled, to produce the biaryl
alcohol 11 and 11a, which were used in the following steps without further purification.
compounds play an important role in medicinal chemistry and drug discovery.
The palladium-catalyzed Suzuki coupling reaction between aryl halides and organoboronic acid is an excellent method for the synthesis of various biaryl
compounds, which constitute a wide range of fine chemicals, pharmaceuticals, and advanced materials [6-10].
