Ding, Siyi published the artcileSilver(I)-mediated oxidation/cyclization of acrylamides with alkyl trifluoroborates, Formula: C8H11NO, the main research area is oxindole preparation silver mediated; acrylamide alkyl trifluoroborate tandem oxidative cyclization.

A mild silver-mediated oxidative cyclization of acrylamides I (R1 = H, 4-MeO, 4-Cl, 2-F; R2 = Me, i-Pr) has been developed by using alkyl trifluoroborates R3BF3K (R3 = i-Bu, EtCOCH2CH2, MeO2CCHMeCH2, cyclopentyl, PhCH2CH2, etc.) as radical precursors. It proceeds through a tandem radical addition/cyclization process, in which two new carbon-carbon bonds were formed. This protocol allows reliable and practical access to build the skeleton of 3,3-disubstituted oxindoles II in moderate yields; the readily available starting reagents, broad substrate scope and mild reaction conditions are the characteristic features of this protocol.

Deng, Xingwang published the artcileRapid Access to Diverse Potassium Acyltrifluoroborates (KATs) through Late-Stage Chemoselective Cross-Coupling Reactions, Product Details of C8H11NO, the main research area is acyl trifluoroborate late stage functionalization coupling amination; Suzuki Sonogashira coupling Buchwald amination acyl trifluoroborate functionalization.

Functionalization of acyltrifluoroborates K[BrArCOBF3] (Ar = arylene, 2,5-thiophenediyl) was achieved by late-stage cross-coupling with arylboronic acids, arylacetylenes and aromatic amines, providing access to substituted trifluoroborates K[RArCOBF3] (R = aryl, alkynyl, arylamino). Potassium acyltrifluoroborates (KATs) are opening up new avenues in chem. biol., materials science, and synthetic organic chem. due to their intriguing reactivities. However, the synthesis of these compounds remains mostly complicated and time-consuming. Herein, we have developed chemoselective Pd-catalyzed approaches for the late-stage diversification of arenes bearing prefunctionalized KATs. These approaches feature chemoselective cross-coupling, rapid diversification, functional group tolerance, mild reaction conditions, simple operation, and high yields.

Liu, Tong published the artcilePhoto-mediated synthesis of halogenated spiro[4,5]trienones of N-aryl alkynamides with PhI(OCOCF3)2 and KBr/KCl, Name: 4-Methoxy-N-methylaniline, the main research area is halospirotrienone preparation green chem photochem; aryl alkynamide phenyliodine bistrifluoroacetate intramol spirocyclization.

A novel and convenient photo-mediated halogenated spirocyclization of N-(p-methoxyaryl)propiolamides has been developed. The photolysis of phenyliodine bis(trifluoroacetate) (PIFA) as an iodination reagent led to iodinated ipso-cyclization under the irradiation of a xenon lamp, while brominated ipso-cyclization or chlorinated ipso-cyclization was achieved by irradiating a mixture of PIFA and KBr/KCl under a blue LED. The present protocol simply utilizes light as the safe and clean energy source and doesn’t require any external photocatalyst providing various 3-halospiro[4,5]trienones in good to excellent yields (up to 93%).

Yi, Xuewen published the artcileCopper-Catalyzed Radical N-Demethylation of Amides Using N-Fluorobenzenesulfonimide as an Oxidant, COA of Formula: C8H11NO, the main research area is copper catalyzed radical demethylation amide fluorobenzenesulfonimide.

An unprecedented N-demethylation of N-Me amides has been developed by use of N-fluorobenzenesulfonimide as an oxidant with the aid of a copper catalyst. The conversion of amides to carbinolamines involves successive single-electron transfer, hydrogen-atom transfer, and hydrolysis, and is accompanied by formation of N-(phenylsulfonyl)benzenesulfonamide. Carbinolamines spontaneously decompose to N-demethylated amides and formaldehyde, because of their inherent instability.
