Cu(OAc)<sub>2</sub>-Promoted Cascade Carboamination/Oxidative Cyclization of <i>C</i>-Acylimines with Alkenes
A Cu(OAc)(2)-promoted cascade carboamination/oxidative cyclization of alkenes with alpha-imino esters has been explored. This transformation provides a concise approach to rapid assembly of 2-oxo-3-iminopyrrole derivatives in moderate to good yields.
