CONTROLLING THE STEREOCHEMISTRY IN 2-OXO-ALDEHYDE-DERIVED UGI ADDUCTS THROUGH THE CINCHONA ALKALOID-PROMOTED ELECTROPHILIC FLUORINATION

Wang, Yuqing; Wang, Gaigai; Peshkov, Anatoly A.; Yao, Ruwei; Hasan, Muhammad; Zaman, Manzoor; Liu, Chao; Kashtanov, Stepan; Pereshivko, Olga P.; Peshkov, Vsevolod A. (Beilstein Journal of Organic Chemistry, 2020-08)

In this report, we introduce a new strategy for controlling the stereochemistry in Ugi adducts. Instead of controlling stereochemistry directly during the Ugi reaction we have attempted to stereodefine the chiral center ...
Gold-catalyzed post-Ugi alkyne hydroarylation for the synthesis of 2-quinolones

Du, Xiaochen; Huang, Jianjun; Nechaev, Anton A.; Yao, Ruwei; Gong, Jing; Van der Eycken, Erik V.; Pereshivko, Olga P.; Peshkov, Vsevolod A. (Beilstein J. Org. Chem., 2018-10-04)

A series of propargylamides containing an electron-rich benzene ring was prepared through the Ugi reaction of 3,5-dimethoxyaniline with various propiolic acids, aldehydes and isocyanides. Subjecting these adducts to a ...
