Chem. Commun., 2018, Advance Article DOI: 10.1039/C8CC01040D, CommunicationQian Yao, Han Yu, Hang Zhang, Shunxi Dong, Fenzhen Chang, Lili Lin, Xiaohua Liu, Xiaoming Feng Here we report an efficient asymmetric cycloaddition of C[double bond, length as m-dash]O double bonds with cyclobutenones catalyzed by a chiralN,N[prime or minute]-dioxide/Yb(III) complex.
