Phosphine-catalyzed [3 + 2] cycloaddition of Morita–Baylis–Hillman carbonates with sulfamate-derived cyclic imines†
Abstract
Phosphine-catalyzed [3 + 2] cycloaddition of Morita–Baylis–Hillman carbonates with sulfamate-derived cyclic imines has been developed, affording sulfamate-fused dihydropyrroles in moderate to good yields.
