One-Pot Au[III]-/Lewis Acid Catalyzed Cycloisomerization of Nitroalkynes and [3 + 3]Cycloaddition with Donor–Acceptor Cyclopropanes

A one-pot protocol for the synthesis of a tricyclic pseudoindoxyl scaffold from 2-nitroalkynylbenzenes, comprising of an Au­(III)-catalyzed nitroalkyne cycloisomerization leading to isatogen and its [3 + 3]-cycloaddition with donor–acceptor cyclopropanes mediated by a suitable Lewis acid, has been d...
