The Ag-promoted α-C-H arylation of alcohols

We herein report the functionalization of α-C-H in alcohols through cross-dehydrogenative coupling reactions. Selectfluor was used as a mild oxidant. In situ-generated HF participated in the reaction and no external strong acid was necessary. A variety of heteroaryl-substituted alcohols were achieved with good yields and with good functional group tolerance.

Hydroxymethylation of quinolinesviairon promoted oxidative C-H functionalization: synthesis of arsindoline-A and its derivatives

Herein, we report a mild and efficient hydroxymethylation of quinolinesviaan iron promoted cross-dehydrogenative coupling reaction under external acid free conditions. Various hydroxyalkyl substituted quinolines were achieved in excellent yields with well tolerated functional groups. Importantly, a few of the hydroxylmethylated quinolines were further transformed into respective aldehydes, and were successfully utilized for the synthesis of alkaloid arsindoline-A and its derivatives.

Discovery of Novel Quinoline-Chalcone Derivatives as Potent Antitumor Agents with Microtubule Polymerization Inhibitory Activity

A series of novel quinoline-chalcone derivatives were designed, synthesized, and evaluated for their antiproliferative activity. Among them, compound 24d exhibited the most potent activity with IC50 values ranging from 0.009 to 0.016 μM in a panel of cancer cell lines. Compound 24d also displayed a good safety profile with an LD50 value of 665.62 mg/kg by intravenous injection, and its hydrochloride salt 24d-HCl significantly inhibited tumor growth in H22 xenograft models without observable toxic effects, which was more potent than that of CA-4. Mechanism studies demonstrated that 24d bound to the colchicine site of tubulin, arrested the cell cycle at the G2/M phase, induced apoptosis, depolarized mitochondria, and induced reactive oxidative stress generation in K562 cells. Moreover, 24d has potent in vitro antimetastasis and in vitro and in vivo antivascular activities. Collectively, our findings suggest that 24d deserves to be further investigated as a potent and safe antitumor agent for cancer therapy.

Spin-Center Shift-Enabled Direct Enantioselective α-Benzylation of Aldehydes with Alcohols

Nature routinely engages alcohols as leaving groups, as DNA biosynthesis relies on the removal of water from ribonucleoside diphosphates by a radical-mediated "spin-center shift" (SCS) mechanism. Alcohols, however, remain underused as alkylating agents in synthetic chemistry due to their low reactivity in two-electron pathways. We report herein an enantioselective α-benzylation of aldehydes using alcohols as alkylating agents based on the mechanistic principle of spin-center shift. This strategy harnesses the dual activation modes of photoredox and organocatalysis, engaging the alcohol by SCS and capturing the resulting benzylic radical with a catalytically generated enamine. Mechanistic studies provide evidence for SCS as a key elementary step, identify the origins of competing reactions, and enable improvements in chemoselectivity by rational photocatalyst design.

Hydroxymethylation of Quinolines with Na2S2O8 by a Radical Pathway

Quinolines and isoquinolines were treated with Na2S2O8 in a mixture of methanol and water at 70 °C to form hydroxymethylated quinolines and isoquinolines in good to moderate yields, under transition-metal-free conditions. The formed hydroxymethyl group was smoothly converted into aldehyde, ester, amide, bromomethyl, (N,N-diethylamino)methyl, cyano, and tetrazole groups, in good yields.

Simple and Clean Photo-induced Methylation of Heteroarenes with MeOH

Heteroarene methylation utilizing a cheap and safe methylation source without involving transition metals represents an important yet challenging objective. Here, a simple and clean catalyst-free protocol for the methylation of various heteroarenes (including six- and five-membered types) is described under light irradiation. This protocol employs cheap, readily available, and abundant MeOH as both the solvent and the methylation source. It was found that adding dichloromethane (DCM) as a co-solvent could significantly increase the yield of the methylation products. Heteroarenes bearing various functional groups could be methylated and tri-deuteromethylated successfully. Deuterium labeling studies suggested that the newly generated methyl group in the products consisted of two hydrogens from the methyl group and one hydrogen from the OH group in MeOH.
