资源简介：
By
using an N-heterocyclic carbene catalyst bearing a hydroxyl
moiety, the asymmetric formal (3 + 2) cyclization of aryl 3-bromoenals
and isatins was achieved to produce a series of chiral spirooxindole–butenolides
including an alkenyl-substituted compound, which underwent benzannulations
with benzynes to form intriguing spirocyclic scaffolds.
