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 A first case of asymmetric catalysis induced by metal-free bisoxazolines.
Metal-free bisoxazolines catalyze the Diels-Alder reaction of N-substituted maleimides with anthrone derivatives leading to products in excellent yields and enantioselectivities up to 70%. A mechanism relying on Broensted-base catalysis is assumed to be involved with formation of an ion pair between the protonated catalyst and the anthrone enolate, which acts as a diene.
After consulting a lot of data, we found that this compound(4144-22-3)Formula: C8H11NO2 can be used in many types of reactions. And in most cases, this compound has more advantages.
