Histone deacetylase 6 (HDAC6) is a promising therapeutic target for the treatment of neurodegenerative disorders. SW-100 (1a), a phenylhydroxamate-based HDAC6 inhibitor (HDAC6i) bearing a tetrahydroquinoline (THQ) capping group, is a highly potent and sel
Visible-Light Induced C(sp2)?H Amidation with an Aryl–Alkyl σ-Bond Relocation via Redox-Neutral Radical–Polar Crossover

We report an approach for the intramolecular C(sp2)?H amidation of N-acyloxyamides under photoredox conditions to produce δ-benzolactams with an aryl-alkyl σ-bond relocation. Computational studies on the designed reductive single electron transfer strategy led us to identify N-[3,5-bis(trifluoromethyl)benzoyl] group as the most effective amidyl radical precursor. Upon the formation of an azaspirocyclic radical intermediate by the selective ipso-addition with outcompeting an ortho-attack, radical–polar crossover was then rationalized to lead to the rearomative ring-expansion with preferential C?C bond migration.

We report the [Ru(p-cymene)(l-proline)Cl] ([Ru1])-catalyzed cyclization of 1,4,2-dioxazol-5-ones to form dihydroquinoline-2-ones in excellent yields with excellent regioselectivity via a formal intramolecular arene C(sp2)-H amidation. The reactions of the 2- and 4-substituted aryl dioxazolones proceeds initially through spirolactamization via electrophilic amidation at the arene site, which is para or ortho to the substituent. A Hammett correlation study showed that the spirolactamization is likely to occur by electrophilic nitrenoid attack at the arene, which is characterized by a negative ρ value of -0.73.

A practical para-C-H functionalization of aniline derivatives has been developed using an in situ generated bulky hypervalent iodinium reagent. Para-iodo, bromo, chloro, nitro, trifluormethyl aniline derivatives can be obtained efficiently, in many cases in 10 min in a transition metal-free manner. Medicinal chemicals or intermediates can be purified without column chromatography or recrystallization, which significantly reduces the waste and simplifies the work-up process.
Revisiting Arene C(sp2)?H Amidation by Intramolecular Transfer of Iridium Nitrenoids: Evidence for a Spirocyclization Pathway

Two mechanistic pathways, that is, electrocyclization and electrophilic aromatic substitution, are operative in most intramolecular C?H amination reactions proceeding by metal nitrenoid catalysis. Reported here is an alternative mechanistic scaffold leading to benzofused δ-lactams selectively. Integrated experimental and computational analysis revealed that the reaction proceeds by a key spirocyclization step followed by a skeletal rearrangement. Based on this mechanistic insight, a new synthetic route to spirolactams has been developed.
Combining Eosin y with Selectfluor: A Regioselective Brominating System for Para-Bromination of Aniline Derivatives
Huang, Binbin,Zhao, Yating,Yang, Chao,Gao, Yuan,Xia, Wujiong
supporting information, p. 3799 - 3802 (2017/07/26)
A mild, metal-free, and absolutely para-selective bromination of aniline derivatives has been developed in excellent yields, wherein the organic dye Eosin Y is employed as the bromine source in company with Selectfluor. Neither air nor moisture sensitive, this facile reaction proceeds smoothly at room temperature and completes within a short time. Mechanistic studies indicate a radical pathway; therefore, the existence of an in situ generated brominating reagent, "Selectbrom", is postulated, which may reasonably account for the unique regioselectivity for the para-bromination of N-acyl- as well as N-sulfonylanilines.

Biocatalytic α-Oxidation of Cyclic Amines and N-Methylanilines for the Synthesis of Lactams and Formamides

, p. 937 - 940 (2017/03/27)
An environmentally friendly method for the synthesis of lactams and formamides through the biocatalytic α-oxidation of amines was developed by employing Pseudomonas plecoglossicida ZMU-T04 as a biocatalyst. In this biocatalytic process, the α-oxidation of cyclic amines and N-methylanilines proceeded smoothly to give the corresponding amides in low to high yields. Furthermore, it was demonstrated that synthetic 3,4-dihydroquinolin-2(1H)-one could be used as a key precursor of antidepressant bioactive molecules. The mechanism of this biocatalytic α-oxidation process was investigated by isotope- labeling experiments.
