Abstract:
Palladium-catalyzed intramolecular direct C–H arylations for the synthesis of hitherto unknown fused hetero systems containing an incorporated pyrrolo[2,3-d]pyrimidine scaffold are described. Pyrimido[5′,4′:4,5]pyrrolo[2,1-a]isoindoles were synthesized from 2,4-di­arylpyrrolo[2,3-d]pyrimidines and o-bromobenzyl bromides by using a cascade N-benzylation/C–H arylation reaction sequence. A series of pyrimido[5′,4′:4,5]pyrrolo[1,2-f]phenanthridines were successfully assembled via a domino process involving the palladium-catalyzed direct double C–H arylation reactions of 2,4,7-triarylpyrrolo[2,3-d]

Abstract:
Intramolecular CH arylation of pyrone, pyridone, uracil, imidazole, and benzimidazole derivatives are carried out in the presence of a Pd catalyst to form potentially bioactive fused heterocyclic compounds, whereas the n-Bu3SnH-mediated aryl radical cyclization of the precursors 3 afforded mainly halogen-reduced uncyclized products.Key words: Pd(0) catalyst, CH arylation, intramolecular cyclization, regioselectivity.

Abstract:
Step-economical syntheses of annulated 1,2,3-triazoles were accomplished through copper-catalyzed intramolecular direct arylations in sustainable one-pot reactions. Thus, catalyzed cascade reactions involving [3 + 2]-azide–alkyne cycloadditions (CuAAC) and C–H bond functionalizations provided direct access to fully substituted 1,2,3-triazoles with excellent chemo- and regioselectivities. Likewise, the optimized catalytic system proved applicable to the direct preparation of 1,2-diarylated azoles through a one-pot C–H/N–H arylation reaction.

Abstract:
N-Arylated aliphatic and aromatic amines are important substituents in many biologically active compounds. In the last few years, transition-metal-mediated N-aryl bond formation has become a standard procedure for the introduction of amines into aromatic systems. While N-arylation of simple aromatic halides by simple amines works with many of the described methods in high yield, the reactions may require detailed optimization if applied to the synthesis of complex molecules with additional functional groups, such as natural products or drugs. We discuss and compare in this review the three mai

Abstract:
The design and synthesis of three different scaffolds of nitrogen heterocycles have been achieved by using either methods described in the literature or newly developed synthetic methodologies/routes. The three synthesised libraries in this thesis were based on Pd-catalysed N-arylations, Castagnoli-Cushman multicomponent reaction, and Rh(II)-catalysed intramolecular C-H insertions. The compounds were successfully synthesised in moderate to excellent yields. Firstly, one of the synthesised diaryl imidazolines was found to be a selective COX-2 inhibitor due to its comparable activity to the appr

It is found that the reaction mechanism actually consists of three steps which are concerted acid-baes reaction, concerted cyclization and removal of the phosphoryl Group, elimination with chlorophosphite as base to form quinoxaline.The first step is rate-determining step because it has the highest energy barrier in gas phase, with relative Gibbs free energy values of 28.36 kcal/mol.
