Selective N-Arylation of Aminobenzanilides under Mild Conditions Using Triarylbismuthanes
摘要:
Diarylamines are prepared selectively in good yields under mild conditions by treatment of aminobenzanilides with triarylbismuthanes in the presence of copper(II) acetate and triethylamine. Arylation under these conditions occurs preferentially at the amino- rather than the amide-nitrogen of the benzanilide. Thus, heating an aminobenzanilide in dichloromethane under reflux in the presence of 1 equiv each of a triarylbismuthane, triethylamine, and copper(II) acetate affords the diarylamine in good yields. This method thereby provides a mild and expeditious route to functionalized diarylamines.

this study, we design a series of theophyllinederivatives as novel ATAD2 inhibitors through fragment-based screening and scaffold growth strategy. A novel potent ATAD2 inhibitor (compound 19f) is discovered with an IC50 value of 0.27 μM against ATAD2, which adopts a combination of classic and atypical binding mode. Additionally, compound 19f could impede ATAD2 activity and c-Myc activation, induced significant
