Lorion, Melanie M. published the artcileCobalt-Catalyzed α-Arylation of Substituted α-Bromo α-Fluoro β-Lactams with Diaryl Zinc Reagents: Generalization to Functionalized Bromo Derivatives, Recommanded Product: Ethylbromofluoroacetate, the publication is Chemistry – A European Journal (2020), 26(58), 13163-13169, database is CAplus and MEDLINE.
A cobalt-catalyzed cross-coupling of α-bromo α-fluoro β-lactams with diarylzinc or diallylzinc reagents is herein disclosed. The protocol proved to be general, chemoselective and operationally simple allowing the C4 functionalization of β-lactams. The substrate scope was expanded to α-bromo lactams and amides, α-bromo lactones and esters as well as N- and O-containing heterocycles.
Chemistry – A European Journal published new progress about 401-55-8. 401-55-8 belongs to bromides-buliding-blocks, auxiliary class Fluoride,Bromide,Aliphatic hydrocarbon chain,Ester, name is Ethylbromofluoroacetate, and the molecular formula is C4H6BrFO2, Recommanded Product: Ethylbromofluoroacetate.
