antitumor activities. (+)-Albaconol, (+)-neoalbaconol, and two (+)-yahazunol isomers (24 and 25) proved to be the novel pharmaceutical leads. The probable macromolecular targets were estimated to deliver new information about the biological potentials resident in (+)-yahazunol relevant products. This work also featured the first synthesis of (+)-albaconol and (+)-neoalbaconol, the first biological exploration

1,2-Benzdiyne equivalents possess the unique property that they can react with two arynophiles through iteratively generated 1,2- and 2,3-aryne intermediates. Upon rational modification on the second leaving group of these aryne precursors, a domino aryne annulation approach was developed through a nucleophilic-ene reaction sequence. Various benzo-fused N-heterocyclic frameworks were achievable under transition metal-free conditions with a broad substrate scope.

Vicinal diamination of domino aryne precursors was achieved with sulfamides. The reaction proceeds through a two-aryne pathway, accepting two N-nucleophiles at the 1,2-positions of an arene ring. Symmetrical and unsymmetrical diaminobenzenes were readily obtained.
