Abstract: Here, a facile and selective synthesis method for cationic azatriphenylene derivatives was established by electrochemical intramolecular cyclization, where atom-economical C–H pyridination without a transition-metal catalyst or an oxidant is a key step. The proposed protocol… read more here.

DOI: 10.1021/acs.orglett.7b03164
Abstract: A novel domino oxidative annulation of 2-vinylanilines with internal alkynes was developed to constitute a rare class of cyclopentaquinoline derivatives. This transformation encompasses four σ bonds formation, one quaternary carbon center construction, and pyridination steps… read more here.
