A copper-catalyzed aerobic 3-hydroxyisoindolinone synthesis was developed via the benzylic double C(sp3)-H functionalization of 2-alkylbenzamides. In this reaction, molecular oxygen was used as both an oxidant for C(sp3)-H functionalization and an oxygen source. Our method can be extended to diverse benzylic C(sp3)-H bonds and shows excellent functional group tolerance. This journal is

2, 4-Disubstituted phthalazin-1(2H)-one derivatives were synthesized via nucleophilic attack of N-2 of phthalazin-1(2H)-one derivatives on different alkyl halides. In addition, reactive phthalazinone acetohydrazide derivative was utilized as a scaffold to synthesize different heterocyclic systems. The assigned structures for all the newly synthesized derivatives were confirmed on the basis of elemental analyses and spectral data. Mechanistic illustrations for some of the synthesized compounds were also discussed. The synthesized compounds were evaluated for in vitro antimicrobial and antitumor activity. Most of the tested compounds exhibited significant potency as antimicrobial and antitumor agents. Moreover, MOE 2014.09 software was utilized to carry out computational studies to support the biological activity results.
Palladium-Catalyzed Decarboxylative ortho-C(sp2)?H Aroylation of N-Sulfoximine Benzamides at Room Temperature
Das, Prasenjit,Biswas, Promita,Guin, Joyram
, p. 920 - 925 (2020/03/04)
A palladium-catalyzed method for the decarboxylative ortho C?H acylation of N-sulfoximine benzamides is developed at room temperature. The catalytic method enables easy access to various functionalized 2-aroylaromatic carboxylic acid derivatives in good isolated yields. Based on our mechanistic studies, a Pd(II)/Pd(IV) catalytic cycle that involves aroyl radical intermediate is proposed for the reaction.

Palladium-Catalyzed Acylation Reactions: A One-Pot Diversified Synthesis of Phthalazines, Phthalazinones and Benzoxazinones
Suchand, Basuli,Satyanarayana, Gedu
, p. 2233 - 2246 (2018/06/04)
A sequential one-pot strategy for the diversified synthesis of phthalazines, phthalazinones and benzoxazinones was presented. This strategy proceeds through [Pd]-catalyzed acylation and nucleophilic cyclocondensation with dinucleophilic reagents. This process was based on direct coupling with simple bench-top aldehydes without the assistance of directing group and without activating the carbonyl group. The process is highly advantageous because it employs simple nitrogen-based nucleophiles, and non-toxic and readily accessible aldehydes as the carbonyl source. Most importantly, the strategy was applied to the one-pot synthesis of PDE-4 inhibitor.
A novel method for heterocyclic amide-thioamide transformations
Fathalla, Walid,Ali, Ibrahim A. I.,Pazdera, Pavel
, p. 174 - 181 (2017/02/15)
In this paper, we introduce a novel and convenient method for the transformation of heterocyclic amides into heteocyclic thioamides. A two-step approach was applied for this transformation: Firstly, we applied a chlorination of the heterocyclic amides to afford the corresponding chloroheterocycles. Secondly, the chloroherocycles and N-cyclohexyl dithiocarbamate cyclohexylammonium salt were heated in chloroform for 12 h at 61°C to afford heteocyclic thioamides in excellent yields.
