Abstract: A family of N,N'-diaryl-N″-(quinolin-8-yl)guanidines were prepared by two methods, and these guanidines were subjected to Co(II)-catalyzed C-H functionalization/annulation with terminal and internal alkynes under mild conditions to afford a family of indole guanidines. Substrates with… read more here.

Abstract: Rh-catalyzed C-H functionalization/annulation of arylamides with maleimides has been accomplished to furnish succinimide-tethered isoquinoline-1,3-diones. The sequential C-C/C-N bond formation, substrate scope, access to quaternary carbon and functional group tolerance are the salient features. read more here.
