Selectfluor-mediated construction of 3-arylselenenyl and 3,4-bisarylselenenyl spiro[4.5]trienones <i>via</i> cascade annulation of <i>N</i>-phenylpropiolamides with diselenides
A cascade annulation of terminal alkynyl amides with diselenides leading to the construction of 3-arylselenenyl spiro[4.5]trienones was realized under mild conditions with Selectfluor as the sole oxidant. Furthermore, 3,4-bisarylselenenyl spiro[4.5]trienones were also synthesized by a cascade annulation reaction using transition-metal copper as a catalyst. This spirocyclization process is suggested
