✦ Synopsis

A Synthesis of Quinoline-5,8-quinones via the Benzannulation of 1,4-Dihydro-2-pyridyl Carbene Complexes.

-Carbene complexes (I), generated by the standard Fischer method upon metallation of the corresponding pyridines, give with alkynes (II) the benzannulated products (III), which can be converted to the title quinolinequinones by a two-step oxidation procedure. -(
