Benzo[de]naphtho[1,8-gh]quinolines: synthesis, photophysical studies and nitro explosives detection
A rational synthetic approach to substituted naphtho[1,8-gh]quinolines using intramolecular cyclization in the presence of potassium in the series of (naphthalen-1-yl)isoquinolines is described. The photophysical properties of the obtained compounds were

Cobalt-Catalyzed ortho-C−H functionalization/alkyne annulation of benzylamine derivatives: Access to dihydroisoquinolines [PDF]
A practical picolinamide-directed C−H functionalization/alkyne annulation of benzylamine derivatives enabling access to the previously elusive 1,4-dihydroisoquinoline skeleton was developed using molecular O2as the sole oxidant and Co(OAc)2as precatalyst.
