Facile and Efficient Synthesis of Hydrophenanthren-1(2H)-ones and Naphtho[2,1-c]furan-3(1H)-ones by a Palladium-Catalyzed Aryne Annulation Strategy

Construction of indazolo[3,2-a]isoquinolines via [3 + 2] cycloaddition of benzynes

A [3 + 2] annulation protocol for the construction of N-substituted indazolo[3,2-a]isoquinolines starting from benzynes and C,N-cyclic azomethine imines was developed. A diverse range of highly functionalized products indazolo[3,2-a]isoquinolines featuring an indazole scaffold can be easily accessed via a one-step reaction under mild conditions, and they show good anti-proliferative activity on cancer cells.

Benzo[c]carbazole derivatives produced by an effective Diels–Alder reaction: synthesis and structure–activity-relationship for surface coating

We demonstrate the use of an effective Diels–Alder reaction to produce a library of heterocyclic, polyaromatic benzo[c]carbazole derivatives with good corrosion inhibitive potency for copper against HCl.

Palladium-catalyzed annulation of arynes by o-halobenzamides: synthesis of phenanthridinones

The palladium-catalyzed annulation of arynes by substituted o-halobenzamides produces N-substituted phenanthridinones in good yields. This methodology provides this important heterocyclic ring system in a single step by simultaneous C-C and C-N bond formation, under relatively mild reaction conditions, and tolerates a variety of functional groups.
