The convergent synthesis of a class of enediyne-imides as well as their palladium-catalyzed branching cyclizations, which can be accomplished in two ways leading to a set of polysubstituted furo[2,3-b]pyridines upon using the N-tosyl carboxamide moiety as an N,O-bisnucleophile, are presented.

The first bimolecular oxygenative annulation of enediyne compounds leading to naphthalene frameworks has been developed by using Pd(OAc)2 as the catalyst in the presence of NaI under O2 (1 atm). This reaction provided efficient access to a class of symmetric core-annulated naphthalenes by the homoannulation of enediyne-imides. Intriguingly, the crossover annulation of enediyne-imides and other functionalized enediynes could also be achieved by the same catalytic system, resulting in the formation of several unsymmetrical naphthalene derivatives. Preliminary mechanistic investigation using 18O isotopic labelling and radical scavengers indicated that radical oxygen incorporation cascades might be involved in this conversion.
