A new synthetic methodology for the synthesis of 5H-dibenzo[a,d]cycloheptenes from ortho-aryl alkynyl benzyl alcohols and arenes via a Tf2O-mediated formal [5+2] annulation reaction, has been achieved. From this transformation, structurally...

An Ag‐catalyzed radical cascade bicyclization/aromatization of C‐linked 1,7‐enynes with 1,3‐dicarbonyls has been achieved, providing a step‐ and atom‐economy approach for the construction of 2,3‐dihydro‐1H‐cyclopenta[a]naphthalenes, an important structural scaffold existed in biologically active compounds. From this transformation, structurally diverse 2,3‐dihydro‐1H‐cyclopenta[a]naphthalenes were obtained in moderate to good yields with high regioselectivity. Moreover, the further product derivatizations were also exemplified.
