Title: Hydroxyl-directed ruthenium-catalyzed C-H bond functionalization: versatile access to fluorescent pyrans. Author: Thirunavukkarasu VS, Donati M, Ackermann L. Journal: Org Lett; 2012 Jul 06; 14(13):3416-9. PubMed ID: 22691029. Abstract: 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.[Abstract] [Full Text] [Related] [New Search]
