Palladium(II)-catalyzed oxidative carbocyclization of aza-enallenes

(Chemical equation presented) Live and let diene: A palladium(II)-catalyzed oxidative carbocyclization reaction of aza-enallenes provides access to potentially valuable heterocyclic dienes. In the presence of a dieneophile during the carbocyclization step, the products can react further in a one-pot cyclization/ Diels-Alder sequence to give polycyclic products. BQ = para-benzoquinone.

Copper-catalyzed N-Allenylation of allylic sulfonamides

Figur Presented Allylic allenic amides have been synthesized via a copper-catalyzed cross-coupling between allylic sulfonamides and bromoallenes in moderate to good yields. Copper(I) thiophene-2-carboxylate (CuTC) was used a source of copper with DMEDA as the ligand. The allenylated products obtained are potential substrates for palladium-catalyzed carbocyclizations.
