Hydroxyl-directed ruthenium-catalyzed C-H bond functionalization: versatile access to fluorescent pyrans.
Hydroxyl-assisted oxidative annulations of alkynes were accomplished with an inexpensive ruthenium(II) complex, delivering fluorescent pyrans via highly site selective as well as chemo- and regioselective C-H/O-H bond functionalizations.
