The N-methylation of amines with methanol in aqueous solution was proposed and accomplished by using a water-soluble metal-ligand bifunctional dinuclear iridium catalyst. In the presence of [(Cp*IrCl)2(thbpym)][Cl]2 (1 mol %), a range of desirable products were obtained in high yields under environmentally benign conditions. Notably, this research exhibited the potential of transition metal-catalyzed
The direct N-monomethylation of aromatic primary amines, including arylamines, arylsulfonamides and amino-azoles, using methanol as a methylating agent has been accomplished in the presence of a [Cp*IrCl2]2/NaOH system. From both synthetic and environmental points of view, the reaction is highly attractive because of low catalyst loading, broad substrate scope and excellent selectivities.

A genus of arylsulfonamide derivatives of heterocyclic constrained tricyclic compounds is disclosed. The compounds are of the following genus: (I). The compounds induce FOXO1 transcription factor translocation to the nucleus by modulating PP2A and, as a consequence, exhibit anti-proliferative effects. They are useful in the treatment of a variety of disorders, including as a therapy in cancer treatment, or used in combination with other drugs to restore sensitivity to chemotherapy where resistance has developed.
