The Pd-catalyzed C?H bond functionalization of lilolidine was investigated. The use of a palladium-diphosphine catalyst associated to acetate bases in DMA was found to promote the regioselective arylation at alpha-position of the nitrogen atom of lilolidine with a wide variety of aryl bromides. From these alpha-arylated lilolidines, a second arylation at the beta-position gives the access to alpha,beta-diarylated lilolidines containing two different aryl groups. The one pot access to alpha,beta-diarylated lilolidines with two identical aryl groups is also possible by using a larger amount of aryl bromide. The synthesis of 5,6-dihydrodibenzo[a,c]pyrido[3,2,1-jk]carbazoles from lilolidine via three successive direct arylations is also described. Therefore, this methodology provides a straightforward access to several lilolidine derivatives from commercially available compounds via one, two or three C?H bond functionalization steps allowing to tune their biological properties.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 1532-97-4, you can also check out more blogs about1532-97-4

The protocol proved compatible with a wide variety of functionalized (hetero)aromatic bromides, as well as several different sterically hindered tertiary alcohols, affording the alkoxycarbonylated products in high yields. Finally, the formation of aromatic trityl esters is discussed.

A simple method for the introduction of a methyl and higher aliphatic group to various heteroarenes using very inexpensive reagents is described. It is based on the radical addition of a carboxylic xanthate followed by decarboxylation. Depending on the heteroarene structure, the decarboxylation can be spontaneous or induced by heating in N,N-dimethylacetamide or N-methyl pyrrolidone in a microwave oven.

4-Dimethylaminopyridine (DMAP) is shown to undergo Pd/PtBu3 catalyzed coupling with aryl halides and carbon monoxide to form electrophilic aroyl-DMAP salts. The reaction is easily scalable to prepare multigram quantities with low catalyst loadings, while the precipitation of these salts as they form leads to products with low impurities. These reagents rapidly react with a variety of nucleophiles, including those that contain potentially incompatible functional groups under standard carbonylative conditions.

We report a highly efficient and chemoselective Minisci-type alkylation reaction of N-heteroarenes with alkanes under the reagent control of a hypervalent iodine oxidant PFBI-OH. In addition to the high reactivity, PFBI-OH demonstrated a high steric sensitivity for H abstraction of alkanes. This reaction is selective for more sterically accessible secondary C-H bonds over weaker tertiary C-H bonds. High selectivity toward penultimate methylene groups was observed for a wide range of acyclic alkanes.

A protocol has been developed for conducting the palladium-catalyzed reductive carbonylation of aryl iodides and bromides using 9-methylfluorene-9- carbonyl chloride (COgen) as a source of externally delivered carbon monoxide in a sealed two-chamber system (COware), and potassium formate as the in situ hydride source. The method is tolerant to a wide number of functional groups positioned on the aromatic ring, and it can be exploited for the isotope labeling of the aldehyde group. Hence, reductive carbonylations run with 13COgen provide a facile access to 13C-labeled aromatic aldehydes, whereas with DCO2K, the aldehyde is specifically labeled with deuterium. Two examples of double isotopic labeling are also demonstrated. Finally, the method was applied to the specific carbon-13 labeling of the beta-amyloid binding compound, florbetaben.

A thiophene bearing a cyclopropyl ketone group at C2 was successfully employed in palladium-catalysed direct arylation. The reaction proceeds regioselectively at C5 without decomposition of the cyclopropyl ketone substituent. These couplings were performed employing as little as 0.5 mol% of ligand-free Pd(OAc)2 catalyst with electron-deficient aryl bromides. A wide variety of functional groups on the aryl bromide such as nitrile, nitro, acetyl, formyl, benzoyl, ester, trifluoromethyl, fluoro or methoxy was tolerated. 2013 Elsevier Science.

The palladium-catalysed direct arylation of pyrazoles with aryl halides, using PdCl(C3H5)(dppb)/KOAc catalyst, reveals a similar reactivity of C4 and C5 CH bonds of pyrazoles, whereas the C3 CH bond is almost unreactive, and gives access in one step to a variety of 4,5-diarylpyrazoles. This CH bond functionalisation reaction tolerates a variety of substituents on the aryl bromide such as nitro, cyano, formyl, propionyl, ester, chloro, fluoro or trifluoromethyl groups.
