1. Gold-catalyzed intermolecular hydroamination of allenes with sulfonamides

Author

Chen Zhang, Shao-Qiao Zhang, Hua-Jun Cai, and Dong-Mei Cui

Subjects
allene, gold catalysis, hydroamination, N-sulfonyl, selectivity, sulfonamide, Science, Organic chemistry, QD241-441
Abstract

A co-catalyst of (PPh3)AuCl/AgOTf for the intermolecular hydroamination of allenes with sulfonamides is shown. The reaction proceeded smoothly under mild conditions for differently substituted allenes giving N-allylic sulfonamides in good yields with high regioselectivity and E-selectivity.

2. Gold-catalyzed oxidation of arylallenes: Synthesis of quinoxalines and benzimidazoles

Author

Dong-Mei Cui, Dan-Wen Zhuang, Ying Chen, and Chen Zhang

Subjects
allene, benzimidazole, gold-catalysis, oxidation, quinoxaline, Science, Organic chemistry, QD241-441
Abstract

A gold-catalyzed oxidation of arylallenes to form α-diketones and aldehydes in good yields is presented. Further directed synthesis of quinoxalines and benzimidazoles, via the condensation of the resulting α-diketones and aldehydes with benzene-1,2-diamine, was achieved in high yields.
