Dong, Shunxi,Feng, Xiaoming,Ge, Shulin,Li, Dawei,Wang, Sijing
, p. 5331 - 5336 (2020)
A highly atroposelective N-acylation reaction of aniline-derived sulfonamides has been developed with chiral isothiourea as the catalyst. This approach provides a facile and efficient route to an array of atropoisomeric sulfonyl substituted anilide produc
Catalytic Enantioselective Synthesis of N-C Axially Chiral Sulfonamides through Chiral Palladium-Catalyzed N-Allylation
Kikuchi, Yuki,Nakamura, Chisato,Matsuoka, Mizuki,Asami, Rina,Kitagawa, Osamu
, p. 8112 - 8120 (2019/06/17)
In the presence of (S,S)-Trost ligand and (allyl-Pd-Cl)2 catalyst, the reaction of allyl acetate with the anionic species prepared from various N-(2-tert-butylphenyl)sulfonamides and NaH proceeded in an enantioselective manner (up to 95% ee) to give optically active N-allylated sulfonamide derivatives possessing an N-C axially chiral structure in high yields.
3,5-Di-t-butylnitrosobenzene as a spin trap for N-arylamidyl free radicals
Bologa, U. L.,Oniciu, D. C.,Ciureanu, M.,Barsan, F.,Ghiviriga, I.,Balaban, A. T.
, p. 71 - 76 (2007/10/02)
Acyl- and benzenesulphonyl-anilines with one or two t-butyl groups in ortho positions generate transient amidyl radicals, which were evidenced by traping with 3,5-di-t-butylnitrosobenzene.Spectral simulation showed the simultaneous presence of two paramag
