By repurposing a typical dopamine D-1/D-5 receptor agonist motif, C1-substituted-N3-benzazepine or benzazecine, into the classical RTK inhibitor 2,4-diaminopyrimidine skeleton, a series of new 2,4-diarylaminopyrimidine analogues (DAAPalogues) were developed. Compounds 7 and 8a were identified possessing high potency against both c-Met and ALK kinases. Compound 8a displayed appreciable antitumor efficacy at the dose of 1 mg/kg in the ALK-driven BF3/EML4-ALK xenograft mice model.

For the first time, silver oxide catalyzed SET-oxidative cyclization of an α-amidinoester tethered with an alkene, leading to a novel cyclopropane-fused cyclic amidine, has been developed. This efficient method permits easy access to the pharmaceutically important 3-azabicyclo[n.1.0]alkane framework, having a quaternary centre. The generality of SET oxidative cyclization using persulfate as a co-oxidant
