In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Asymmetric synthesis of heterocyclic chloroamines and aziridines by enantioselective protonation of catalytically generated enamines, published in 2021, which mentions a compound: 1827-27-6, Name is 5-Amino-2-fluoropyridine, Molecular C5H5FN2, Safety of 5-Amino-2-fluoropyridine.
We report a method for the synthesis of chiral vicinal chloroamines via asym. protonation of catalytically generated prochiral chloroenamines using chiral Bronsted acids. The process is highly enantioselective, with the origin of asymmetry and catalyst substituent effects elucidated by DFT calculations We show the utility of the method as an approach to the synthesis of a broad range of heterocycle-substituted aziridines by treatment of the chloroamines with base in a one-pot process, as well as the utility of the process to allow access to vicinal diamines.
