Title: ChemInform Abstract: Enantioselective Michael Addition of 4‐Hydroxycoumarins to β,γ‐Unsaturated α‐Oxophosphonates Catalyzed by a Bifunctional Squaramide Bearing a Structurally Rigid 9,10‐Ethylene‐9,10‐dihydroanthracene Skeleton.
Abstract: Abstract The structurally rigid, new bifunctional squaramide organocatalyst shown demonstrates great advantages over previously reported thiourea or squaramide catalysts in terms of activity and enantioselectivity in the title Michael addition reaction.
