A catalytic asymmetric hetero-Diels-Alder reaction of olefinic azlactones and isatins: Facile access to chiral spirooxindole dihydropyranones

Gao, Tai-Ping,Lin, Jun-Bing,Hu, Xiu-Qin,Xu, Peng-Fei

supporting information, p. 8934 - 8936 (2014/08/05)

A catalytic asymmetric hetero-Diels-Alder (HDA) reaction has been achieved through hydrogen-bond directed γ-addition of olefinic azlactones to isatins. This methodology provides an efficient access to spirooxindole dihydropyranones in moderate to good yie
