Li, Jia published the artcileMetal-free aminohalogenation of quinones with alkylamines and NXS at room temperature, Computed Properties of 73874-95-0, the main research area is halo amino naphthalenedione preparation; naphthoquinone amine aminohalogenation; NXS; aminohalogenation; metal-free; quinones; radical reactions.
A simple and practical strategy for intermol. aminohalogenation of quinone with alkyl amines and NXS was developed for preparation of halo(amino)naphthalenediones I [X = H, Cl, Br, I; R1 = Me; R2 = 2-cyanoethyl, (4-bromophenyl)methyl, phenethyl, (3S)-3-(2-methylphenoxy)-3-phenyl-propyl; R1 = R2 = (CH2)2O(CH2)2, (CH2)2CH(OH)(CH2)2, (CH2)2CH(CO2Me)(CH2)2], in which haloamines generated in situ were employed as bifunctional reagents. The reaction system was reliable, efficient and wide in substrate range, which was suitable for the two-fold aminochlorination of 1, 4-benzoquinones, large-scale reaction and late-stage modification of pharmaceuticals.
Frontiers in Chemistry (Lausanne, Switzerland) published new progress about Halogenation (amino). 73874-95-0 belongs to class piperidines, name is tert-Butyl piperidin-4-ylcarbamate, and the molecular formula is C10H20N2O2, Computed Properties of 73874-95-0.
