Even though immunotherapy has radically changed the search for anticancer therapies, there are still many different pathways that are open to intervention with traditional small molecules. To expand our investigation in the anticancer field, we report here a new series of compounds in which our previous pyrazole and imidazopyrazole scaffolds are linked to a differently decorated phenyl ring through

scaffolds (pyrazole and imidazopyrazole) and the substituted catechol moiety were determinant for the pharmacodynamic properties, even if hybrid molecules bearing to the pyrazoleseries were more active than the imidazopyrazole ones. In addition, the pivotal role of the catechol substituents has been analyzed. In conclusion the hybridization approach gave a new serie of multitarget antiinflammatory compounds

Cascades of cyclic sulfonyimines mediated by tBuOK with diaryliodonium salts has been developed, giving the diaryl ethers in good yields. Furthermore, bulky ortho-substituted diaryl ethers with an aldehyde group can be obtained easily in comparision with metal-catalyzed protocols.
