title: Highly regioselective Lewis acid-catalyzed [3+2] cycloaddition of alkynes with donor-acceptor oxiranes by selective carbon-carbon bond cleavage of epoxides.
abstract: A novel, efficient, highly regioselective Sc(OTf)(3)-catalyzed [3+2] cycloaddition of electron-rich alkynes with donor-acceptor oxiranes via highly chemoselective C-C bond cleavage under mild conditions was developed.
