Abstract: Asymmetric cross-electrophile difunctionalization of tethered alkenes has become a powerful tool for the production of chiral cyclic scaffolds; however, the current studies all focus on carbocyclization reactions. Herein, we report an N-cyclization-alkylation reaction and thus… read more here.

Abstract: 1,2,5-Trisubstituted 7-azaindoles are rapidly and efficiently prepared in a one-pot, copper-free alkynylation–cyclization–alkylation sequence starting from unprotected 2-aminopyridyl halides in a consecutive three-component fashion. By extension to a consecutive four-component coupling–cyclization–iodination–alkylation synthesis of 3-iodo-1-methyl-2-phenyl-1H-pyrrolo[2,3-b]pyridine, a concise… read more here.
