Among the most efficient procedures for indole system synthesisare methods starting from 2-ethynylaniline derivatives, which areeasily prepared and modified, and can be heteroannulated to givethe indole system by many types of reagents, among the most frequentlyused being palladium complexes [7-10] and,more recently, copper salts. [11] Aspart of a broader synthetic programme on indoles, we herein describea copper-mediated heteroannulation of o- ...
