Author is Han, Chunhua; Fu, Zhiyuan; Guo, Songjin; Fang, Xinxin; Lin, Aijun; Yao, Hequan.

A palladium-catalyzed remote 1,n-arylamination (from 1,3- to 1,11-arylamination) of unactivated terminal alkenes with aryl iodides and arylamines has been realized. This three-component reaction proceeded via Pd-catalyzed Heck arylation, alkene isomerization, and aza-Michael addition, exhibiting good regio- and chemoselectivity, and wide substrate scope. Preliminary mechanistic studies indicated that the in situ generated ortho/para-quinone methide intermediates served as the driving force for the alkene isomerization and promoted the rearomatization upon nucleophilic amination.

Inhibitors of checkpoint kinase 1 (CHK1) are of current interest as potential antitumor agents, but the most advanced inhibitor series reported to date are not orally bioavailable. A novel series of potent and orally bioavailable 3-alkoxyamino-5-(pyridin-2-ylamino)pyrazine-2-carbonitrile CHK1 inhibitors was generated by hybridization of two lead scaffolds derived from fragment-based drug design and optimized for CHK1 potency and high selectivity using a cell-based assay cascade. Efficient in vivo pharmacokinetic assessment was used to identify compounds with prolonged exposure following oral dosing. The optimized compound I (CCT244747) was a potent and highly selective CHK1 inhibitor, which modulated the DNA damage response pathway in human tumor xenografts and showed antitumor activity in combination with genotoxic chemotherapies and as a single agent.
