Synthesis and reactivity of a 9-membered azaenediyne: importance of proximity effect in N-alkylation.

Chem Commun (Camb)

Bioorganic Laboratory, Department of Chemistry, Indian Institute of Technology, Kharagpur, India.

Published: April 2006

Synthesis of a 9-membered azaenediyne has been achieved for the first time via intramolecular N-alkylation; the importance of proximity of the reacting centres via cobalt carbonyl complexation of the acetylenic moiety and not the activation of propargylic carbon has been demonstrated.
