RESUMO
Gold(I)-catalyzed efficient synthetic transformation was achieved to access the tetrahydrobenzo[h]cyclopropa[c]chromenes from allyl-substituted 1,6-diynes. Cyclopropane-fused tetrahydrobenzochromenes were obtained regioselectively in ≤92% yields. In this atom-economic organic transformation, three new C-C bonds were formed sequentially in one pot.
