A palladium-catalyzed chemoselective aminomethylative cyclization and aromatizing allylic amination of enyne-tethered allylic alcohols with aminals is described. Under the reaction conditions, the cationic vinyl allylpalladium species undergoes selective migratory insertion of alkenes rather than reductive elimination with nucleophiles. This strategy provides an efficient and unique approach to the construction of functionalized naphthalenes, which are important building blocks in synthetic organic chemistry. Mechanistic studies have revealed that the selective sequential migratory insertion of enyne and alkene is crucial for the cyclization.

An original and mild synthetic route for the preparation of novel azafluorenones and derivatives via a ruthenium-mediated [2 + 2 + 2] cycloaddition of α,ω-diynes and cyanamides has been developed. This atom-economical catalytic process demonstrated remarkable regioselectivities to access fluorescent azafluorenone derivatives. The photophysical properties of azafluorenone derivatives have been evaluated, and photoluminescence phenomena at solid and liquid states have been highlighted.
