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.Jiang, Zhiyong; Pan, Yuanhang; Zhao, Yujun; Ma, Ting; Lee, Richmond; Yang, Yuanyong; Huang, Kuo-Wei; Wong, Ming Wah; Tan, Choon-Hong researched the compound: 1-(tert-Butyl)-1H-pyrrole-2,5-dione( cas:4144-22-3 ).Formula: C8H11NO2.They published the article 《Synthesis of a Chiral Quaternary Carbon Center Bearing a Fluorine Atom: Enantio- and Diastereoselective Guanidine-Catalyzed Addition of Fluorocarbon Nucleophiles》 about this compound( cas:4144-22-3 ) in Angewandte Chemie, International Edition. Keywords: stereoselective guanidine catalyzed conjugate addition fluorocarbon nucleophiles; crystallog chiral adduct quaternary carbon center fluorine atom. We’ll tell you more about this compound (cas:4144-22-3).
The title reaction provides adducts having quaternary carbon centers bearing a fluorine atom with high ee and d.r. values (see scheme). The mechanism and origin of stereoselectivity were elucidated by DFT calculations The bifunctional mode of the guanidine catalysis was demonstrated in the transition states resulting from the DFT results.
