COA of Formula: C8H11NO2. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 1-(tert-Butyl)-1H-pyrrole-2,5-dione, is researched, Molecular C8H11NO2, CAS is 4144-22-3, about Chiral Bicyclic Guanidine-Catalyzed Enantioselective Reactions of Anthrones.
Chiral bicyclic guanidine I was found to be an excellent catalyst for reactions between anthrones and various dienophiles. The catalyst can tolerate a range of substituents and substitution patterns, making several anthrone derivatives suitable for this reaction. Both Diels-Alder and Michael adducts were obtained in excellent yields, high regioselectivities, and high enantioselectivities. This is the first case of a highly enantioselective base-catalyzed anthrone Diels-Alder reaction.
