Chiral Bisguanidine-Catalyzed Inverse-Electron-Demand
Hetero-DielsÀAlder Reaction of Chalcones with Azlactones
[Journal of the American Chemical Society 2010, 132, 10650–10651.
DOI: 10.1021/ja1046928]. Shunxi Dong, Xiaohua Liu, Xiaohong Chen,
Fang Mei, Yulong Zhang, Bo Gao, Lili Lin, and Xiaoming Feng*
Page 10651 and Supporting Information page S-74. The
structure of the proposed transition state in Figure 1 was
incorrect and should be shown as follows:
Figure 1. Proposed transition state for the IEDDA reaction of chalcone
3a with azlactone 4a.
This has also been corrected in the Supporting Information.
We apologize for these mistakes.
