Organocatalytic asymmetric Michael addition of 3-substituted oxindoles to α,β-unsaturated acyl phosphonates for the synthesis of 3,3′-disubstituted oxindoles with chiral squaramides

Yong You, Jian Zuo, Wei-Cheng Yuan, Jian-qiang Zhao, Xiao-Mei Zhang, Xiao-Ying Xu, Ming-Liang Zhang, Lin Chen
Org. Biomol. Chem. | 2015 | 10.1039/C5OB00317B

A highly enantioselective Michael addition of 3-monosubstituted oxindoles to α,β-unsaturated acyl phosphonates with chiral squaramides as catalysts is investigated for the first time. A wide range of 3,3′-disubstituted oxindole adducts bearing adjacent...
