We report an unprecedented organocatalytic enantioselective acyloin rearrangement of alpha,alpha-disubstituted alpha-hydroxy acetals. In the presence of a catalytic amount of chiral binol-derived N-triflyl phosphoramide, alpha-hydroxy acetals rearranged to ...
An enantioselective pinacol rearrangement of functionalized (E)-2-butene-1,4-diols was developed. In the presence of a catalytic amount of a chiral BINOL-derived N-triflyl phosphoramide, these 1,4-diols rearranged to b,g-unsaturated ketones in excellent yi ...
A copper-catalyzed enantioselective arylative semipinacol rearrangement of allylic alcohols was developed. In the presence of a catalytic amount of an in situ generated chiral copper-bisoxazoline complex, reaction of allylic alcohols with diaryliodonium sa ...
As a promising cathode inheritor for lithium-ion batteries, the sulfur cathode exhibits very high theoretical volumetric capacity and energy density. In its practical applications, one has to solve the insulating properties of sulfur and the shuttle effect ...
The development of enantioselective pinacol rearrangement is extremely challenging due to the likelihood involvement of the carbenium intermediate that renders the stereochemical communication between catalyst and substrate difficult to achieve. Herein, we ...
