Shibuya, Tetsuro; Nakamura, Kyosuke; Tanaka, Ken published the artcile< Cationic gold(I) axially chiral biaryl bis[phosphine] complex-catalyzed atroposelective synthesis of heterobiaryls>, Related Products of 139139-86-9, the main research area is heterobiaryl atropisomer preparation; naphthopyran benzoquinoline naphthalenyl biaryl atropisomer preparation; asymmetric catalysis; axial chirality; gold; heterobiaryls; hydroarylation.
It has been established that a cationic gold(I)/(R)-DTBM-Segphos or (R)-BINAP complex catalyzes an atroposelective intramol. hydroarylation of alkynes leading to enantioenriched axially chiral 4-aryl-2-quinolinones and 4-(aryl)coumarins and the synthesis of the target compounds was achieved with up to 61% ee.
Beilstein Journal of Organic Chemistry published new progress about Atropisomers. 139139-86-9 belongs to class chiral-phosphine-ligands, and the molecular formula is C44H40P2, Related Products of 139139-86-9.
