Jiang, Peng-Ying; Fan, Kai-Fang; Li, Shaoyu; Xiang, Shao-Hua; Tan, Bin published the artcile< Metal-free oxidative cross-coupling enabled practical synthesis of atropisomeric QUINOL and its derivatives>, Application In Synthesis of 3893-18-3, the main research area is atropisomeric QUINOL chemoselective preparation; isoquinoline naphthol oxidative cross coupling metal free; QUINOL oxide enantioselective preparation; racemic QUINOL oxide kinetic resolution NHC catalyst.
A direct oxidative cross-coupling reaction between isoquinolines and 2-naphthols, providing a straightforward and scalable route to acquire privileged QUINOL scaffolds I [R1 = H, 7-Me, 6-Ph, etc.; R2 = H, 3-Me, 5-Br, etc.] in a metal-free manner was reported. Moreover, a NHC-catalyzed kinetic resolution of QUINOL N-oxides with high selectivity factor was established to access two types of promising axially chiral Lewis base catalysts in optically pure forms. The utility of this methodol. was further illustrated by facile transformations of products into QUINAP, an iconic ligand in asym. catalysis.
