资源简介：
The Sc(OTf)3-catalyzed
[3 + 2]-annulation reaction between
cyclopropenones and donor–acceptor cyclopropanes is described.
The process leads directly to the formation of 4-oxaspiro[2.4]hept-1-ene
derivatives in good to excellent reaction yields. Density functional
theory calculations suggest that the [3 + 2]-annulation pathway is
strongly preferred over the possible [3 + 3]-process.
