9. Lewis Basic Selenium Catalyzed Chloroamidation of Olefins Using Nitriles as the Nucleophiles.

Author

Tay, Daniel Weiliang, Tsoi, Ivan Tan, Er, Jun Cheng, Leung, Gulice Yiu Chung, and Yeung, Ying-Yeung

Abstract

A Lewis base catalyzed chloroamidation of olefinic substrates was achieved using diphenyl selenide as the catalyst. The reaction conditions are mild and suitable for a wide range of substrates including those which are acid labile. [ABSTRACT FROM AUTHOR]

10. Desymmetrization of diolefinic diols by enantioselective amino-thiocarbamate-catalyzed bromoetherification: synthesis of chiral spirocycles.

Author

Tay DW, Leung GY, and Yeung YY

Abstract

A facile, efficient, and highly diastereo- and enantioselective bromoetherification of diolefinic diols has been developed using an amino-thiocarbamate catalyst. Further manipulations of the bromoether products enabled entry into a new class of spirocycles which are distinctively lacking in the literature., (© 2014 WILEY-VCH Verlag GmbH & Co.
