Recommanded Product: 4144-22-3. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 1-(tert-Butyl)-1H-pyrrole-2,5-dione, is researched, Molecular C8H11NO2, CAS is 4144-22-3, about A 2-(1-methylhydrazinyl)pyridine-directed C-H functionalization/spirocyclization cascade: facile access to spirosuccinimide derivatives. Author is Zhao, Hua; Shao, Xiaoru; Wang, Taimin; Zhai, Shengxian; Qiu, Shuxian; Tao, Cheng; Wang, Huifei; Zhai, Hongbin.
A cobalt-catalyzed oxidative coupling of benzoic hydrazides with maleimides by utilizing 2-(1-methylhydrazinyl)pyridine as a bidentate directing group has been developed. This C-H functionalization/spirocyclization cascade protocol shows high efficiency and remarkable functional group tolerance, and the ubiquitous spirosuccinimides were obtained in good to excellent yields with high regioselectivity. This strategy also provides a novel and efficient access to diverse sym. and unsym. bisspirosuccinimides.
