Financial support from the Fundamental Research Funds for the Central Universities （No. KYZ201749） and the National Natural Science Foundation of China （Nos. 21272119, J1103306） are gratefully acknowledged.
A phosphine-catalyzed [4＋2] annulation of a-substituted allenoate with exocyclic alkene moiety of oxindoles or indan-1,3-diones has been developed. Thus, under the catalysis of PPh3 （20 mol%）, a series of spirooxin...
