A straightforward synthetic pathway to phenanthro[9,10-d]heterocycles

A series of new 4,5-o,o-bis(haloaryl)pyrazoles was regioselectively prepared by a tandem amine exchange/heterocyclization. The intramolecular Stille-type biaryl coupling of the so-obtained pyrazole derivatives and previously prepared diarylisoxazoles led with high overall yields to the isolation of new phenanthro[9,10-d]pyrazoles and phenanthro[9,10- d]isoxazoles, respectively. The formation of dehalogenation products was efficiently avoided by use of heavy-wall pressure tubes.
