Chiral binaphthylthiophosphoramide - Cu(I)-catalyzed asymmetric addition of diethylzinc to N-sulfonylimines

In the presence of a catalytic amount of chiral binaphthylthiophosphoramide L2 (6 mol %) and Cu(I) (3 mol %), the asymmetric addition of diethylzinc to N-sulfonylimines could be achieved in good yields with moderate to high ee (63-93% ee) at 0 °C in tolue

Manganese=Catalyzed Achmatowicz Rearrangement Using Green Oxidant H2O2

Oxidation reactions have been extensively studied in the context of the transformations of biomass=derived furans. However, in contrast to the vast literature on utilizing the stoichiometric oxidants, such as m=CPBA and NBS, catalytic methods for the oxidative furan=recyclizations remain scarcely investigated. Given this, we report a means of manganese=catalyzed oxidations of furan with low loading, achieving the Achmatowicz rearrangement in the presence of hydrogen peroxide as an environmentally benign oxidant under mild conditions with wide functional group compatibility.

Synthesis of 2-aza-1-cyano-4-hydroxyanthraquinones

Phthalide annulation of 2-alkylpyridin-3-ones results in the formation of the unexpected 2-aza-1-cyano-4-hydroxy-anthraquinones, the cyano moiety originating from the 3-cyanophthalide. These compounds hold great potential against Epstein-Barr Virus Early

An efficient synthesis of furyl sulfonamides from the reaction of furan with in situ generated N-tosyl imines

Treatment of an aldehyde and furan with N-sulfinyl-p-toluenesulfonamide/zinc chloride leads to the formation of furyl sulfonamides via an in situ generated N-tosyl imine intermediate. In one case, a novel 4-tosylamino-5,6-dihydro-4H-3-oxa-benz[e]azulene w

An efficient preparation of optically active α-furfuryl amide by kinetic resolution using the modified Sharpless asymmetric epoxidation reagents

Kinetic resolution of α-furfuryl amide was first carried out by using the modified Sharpless asymmetric epoxidation reagent to give the slow-reacting enantiomers, (S)-1(a-h) and (R)-1(b,f) in high enantioselectivity (90-100% e.e) and high chemical yield (

An efficient preparation of optically active α-furfuryl amide by kinetic resolution using the modified sharpless asymmetric epoxidation reagent

Kinetic resolution of α-furfuryl amide was first carried out by using the modified Sharpless asymmetric epoxidation reagent to give the slow-reacting enantiomers, (S)-la-f and (R)-lb,f in high enantioselectivity (90-100% e.e) and high chemical yield (45-5
