资源简介：
A novel
gold(I)-catalyzed polycyclization of easily prepared linear
dienediynes has been developed for the construction of fused 5,7,6-tricyclic
ring systems in one step with high diastereocontrol. The polycyclization,
a formal [4 + 3]/C–H activation reaction, takes place through
gold(I)-catalyzed intramolecular cyclopropanation of diene with diyne,
Cope rearrangement of cis-alkenylalkynylcyclopropane,
aliphatic C–H activation via a seven-membered-ring allene intermediate,
and [1,2]-H and -G (H or OAc) shifts.
