Comprehensive Summary The trifluoromethoxy functional group has received increasing attention in recent years due to its distinctive properties such as good metabolic stability, appropriate lipophilicity and special electrical properties. Thus, the development of new reagents strategies direct trifluoromethoxylation are attracting enthusiasm many fluorine chemical workers. At present, nucleophilic radical trifluoromethoxylating have made major breakthroughs, greatly promoting chemistry. This...
A feasible arylaminomethyl radical-triggered tandem annulation reaction has been developed toward a large variety of poly fused heterocycles, tetrahydroimidazo[1,5-a]quinoxalin-4(5H)-ones, by reacting diverse quinoxalin-2(1H)-ones with various N-arylglycines in green solvent (DMC) the presence CsPbBr3 under white-light irradiation conditions.
Abstract Radical cascade cyclization of β,γ‐unsaturated hydrazones/oximes has recently emerged as an efficient and powerful protocol for the construction diverse valuable functionalized pyrazolines isoxazolines. In this review, three catalytic ways radical are summarized classified; these transition‐metal‐catalyzed systems, transition‐metal‐free photo‐/electrocatalytic respectively. Through methods, various functional groups installed on pyrazoline isoxazoline skeletons to enrich small...
Abstract A convenient radical cascade cyclization of aniline‐linked 1,7‐enynes with 1,3‐dicarbonyl compounds was developed to synthesize cyclopenta[ c ]quinolines in the presence AgNO 3 /K 2 S O 8 . wide range were prepared moderate excellent yields. magnified image
A tetrabutylammonium decatungstate (TBADT)-photocatalyzed direct coupling of inert alkanes and quinoxalin-2(1 H )-ones with 2 evolution was developed at room temperature.
A tetrabutylammonium decatungstate (TBADT) mediated photocatalytic controllable aroylation or diaroylation of allyl sulfones was established to synthesize β,γ-unsaturated ketones and 1,5-diketones in moderate excellent yields, respectively.
The construction of optically pure benzyl trifluoromethoxy (OCF3) compounds continues to present challenges, due limited enantioselectivity‐control or the necessity for OCF3‐containing substrates only two previous reports. Herein, we have developed a salen‐Co‐catalyzed enantioselective hydrotrifluoromethoxylation reaction involving aromatic alkenes and trifluoromethyl arylsulfonate (TFMS). This method effectively produces range chiral with enantiomeric excesses ranging from 75% 99%.

Abstract An efficient and convenient silver‐catalyzed procedure was developed for the synthesis of various phosphoryl‐substituted benzimidazo[2,1‐ a ]isoquinoline‐6(5 H )‐ones from diarylphosphine oxides 2‐arylbenzoimidazoles. Moreover, indolo[2,1‐ ]isoquinolin‐6(5 could also be achieved by using this strategy under mild reaction conditions in presence AgNO 3 /K 2 S O 8 .
Abstract A visible‐light‐induced dioxygenation of β , γ ‐unsaturated oximes for the synthesis diverse useful isoxazolines bearing a hydroxyl moiety was developed by employing graphitic carbon nitride (g‐C 3 N 4 ) as heterogeneous photocatalyst under an air atmosphere. Noted that, eminent advantages this metal‐free protocol include step economy, easy operation, recyclable photocatalyst, external reductant‐/oxidant‐free and mild reaction conditions. Additionally, mechanistic studies indicated...
An effective and simple visible light-induced heterogeneous g-C3N4-catalyzed decarboxylative reaction of quinoxalin-2(1H)-ones with N-aryl glycines was developed. When the performed in DMSO/H2O EtOH, products dihydroquinoxalin-2(1H)-ones tetrahydroimidazo[1,5-a]quinoxalin-4(5H)-ones were unprecedentedly obtained good yields, respectively. This solvent-dependent system offers advantages, including easy operation, short time, high chemoselectivity, a recyclable catalyst,...
