Diastereodivergent Catalytic Asymmetric Michael Addition of 2-Oxindoles to α,β-Unsaturated Ketones by Chiral Diamine Catalysts

Autor: Xinxin Wu, Zunwu Liu, Bubing Zeng, Shigang Wen, Yuan Wei, Jinxing Ye

Publikováno v: Organic Letters. 17:2732-2735

A diastereodivergent catalytic asymmetric Michael addition of 2-oxindoles to α,β-unsaturated ketones has been successfully developed with two complementary chiral diamine catalysts, affording chiral 3,3-disubstituted oxindoles with two adjacent chi

Catalytic Asymmetric Construction of Chiral Hydropyridazines via Conjugate Addition of N-Monosubstituted Hydrazones to Enones

Autor: Wenbin Wu, Zunwu Liu, Xiaoqian Yuan, Junzhu Lu, Yuan Wei, Xinxin Wu, Juan Hu, Jinxing Ye

Publikováno v: Organic Letters. 15:4524-4527

The first example of a highly enantioselective and scalable formal diaza-ene reaction between N-monosubstituted hydrazones and enones catalyzed by a simple chiral primary-second diamine salt has been developed. The catalytic process provides a highly
