Cascade C–H functionalization/annulation of 2-aryl-1,3-dicarbonyls with Morita–Baylis–Hillman adducts: access to α-iso-/benzochromenyl acrylates†
Abstract
Pd-catalyzed site-selective C–H functionalization/annulation of 2-aryl-1,3-dicarbonyls with Morita–Baylis–Hillman adducts has been accomplished to produce α-iso-/benzochromenyl acrylates. The cascade C–C and C–O bond formation, product selectivity, substrate scope and functional group tolerance are the important practical features.
