Synthesis of chalcones via domino dehydrochlorination/Pd(OAc)2-catalyzed Heck reaction

A new method has been developed for the cross-coupling of aryl halides with β-chloroalkyl aryl ketones and their ester and amide analogs through a domino dehydrochlorination/Pd(OAc)2- catalyzed Heck reaction sequence. The enone intermediates generated in situ reduced the occurrence of side reactions and therefore enhanced the efficiency of the reaction. This reaction exhibited good tolerance to various functional groups on both substrates and provides rapid access to a wide range of chalcone derivatives.

Photoredox Cyclization of N-Arylacrylamides for Synthesis of Dihydroquinolinones

Metal- and additive-free photoredox cyclization of N-arylacrylamides is herein reported that provides a concise access to the formation of dihydroquinolinones. In this protocol, sustainable visible light was used as the energy source, and the organic light-emitting molecule 4CzIPN served as the efficient photocatalyst. This reaction system features exclusive 6-endo-trig cyclization selectivity with a generally good yield of a range of functionalized dihydroquinolinones and dihydrobenzoquinolinones. Mechanistical studies reveal the feasibility of both 1,3-H shift and intersystem crossing of the diradical intermediate.

Rh(i)-Catalyzed regioselective arylcarboxylation of acrylamides with arylboronic acids and CO2

The first Rh(i)-catalyzed regioselective arylcarboxylation of electron-deficient acrylamides with arylboronic acids under atmospheric pressure of CO2 has been developed. A range of acrylamides and arylboronic acids were compatible with this reaction under redox-neutral conditions, leading to a series of malonate derivatives that are versatile building blocks in organic syntheses.

Silver-catalyzed radical tandem cyclization for the synthesis of 3,4-disubstituted dihydroquinolin-2(1 H)-ones

A silver-catalyzed tandem decarboxylative radical addition/cyclization of N-arylcinnamamides with aliphatic carboxylic acids is reported. This method affords a novel and straightforward route to various 3,4-disubstituted dihydroquinolin-2(1H)-ones in aque

The synthesis of 3,4-disubstituted dihydroquinolin-2(1H)-one under metal-free conditions in aqueous solution

A novel route toward 3,4-disubstituted dihydroquinolin-2(1H )-ones via radical process has been developed in aqueous solution without metals. This method offers a new and simple route for the synthesis of skeleton of dihydroquinolin-2(1H )-one in one step

Silver-catalyzed radical tandem cyclization: An approach to direct synthesis of 3-acyl-4-arylquinolin-2(1 H)-ones

A silver-catalyzed efficient and practical synthesis of 3-acyl-4-arylquinolin-2(1H)-ones or 3-acyl-4-aryldihydroquinolin-2(1H)-ones through intermolecular radical addition/cyclization in aqueous solution is reported. This method provides a novel, highly e
