Asymmetric construction of quaternary stereocenters by direct organocatalytic amination of 3-substituted oxindoles

Zi-Qing Qian, Feng Zhou, Tai-Ping Du, Bo-Lun Wang, Miao Ding, Xiao-Li Zhao and Jian Zhou

Quinidine derivative (QD)2PYR was found to catalyze the asymmetric direct amination of unprotected prochiral 3-oxindole with DIAD to construct quaternary stereocenters at the C3 position with excellent enantioselectivity.
