C-H cycloamination of N-aryl-2-aminopyridines and N-arylamidines catalyzed by an in situ generated hypervalent iodine(iii) reagent

A metal-free synthesis of diversified pyrido[1,2-a]benzimidazoles and 1H-benzo[d]imidazoles from N-aryl-2-aminopyridines and N-arylamidines has been developed. The C-H cycloamination reaction was catalyzed by hypervalent iodine(iii) species generated in situ from iodobenzene (catalytic) and peracetic acid (stoichiometric). The reaction proceeded smoothly at ambient temperature to provide the corresponding N-heterocycles in good to excellent yields.

Regioselective syntheses of 2,3-substituted pyridines by orthogonal cross-coupling strategies

2-Aryl/alkylamino-3-aryl I and 3-aryl/alkylamino-2-aryl pyridines II, as important potentially bioactive compounds, were synthesized by applying orthogonal cross-coupling strategies. Combinations of the Suzuki-Miyaura, Liebeskind-Srogl, and Buchwald-Hartwig protocols gave access to the title compounds in a straightforward and operationally simple manner. Full control over the regioselectivity at the 2- and 3-positions was achieved by using 2,3-dichloropyridine or 3-iodo-2-(methylthio)pyridine as simple, commercially available starting materials. Within this contribution, efficient and high yielding conditions were developed for the Suzuki-Miyaura cross-coupling reaction of 2-substituted 3-chloropyridines, a transformation formerly underrepresented in the literature. For the synthesis of 3-alkyl/arylamino-2- aryl pyridines, the stability of the methylthio group was exploited under Pd-catalysis in the absence of a copper source. This even enabled the development of an operationally highly facile (semi)-one-pot protocol to access the aforementioned compound class that avoided one purification step. A series of products I and II was prepared by using the developed protocols with excellent regioselectivity and good yields. Copyright

One-pot synthesis of α-carbolines via sequential palladium-catalyzed aryl amination and intramolecular arylation

A one-pot synthesis of α-carbolines via a palladium-catalyzed aryl amination followed by intramolecular arylation is described. 2,3-Dichloro- and 2,3-dibromopyridines have been shown to react with readily available anilines to obtain various substituted α-carbolines in moderate to excellent yields.

Synthesis of α-carbolines starting from 2,3-dichloropyridines and substituted anilines

9H-α-Carbolines have been prepared via consecutive intermolecular Buchwald-Hartwig reaction and Pd-catalyzed intramolecular direct arylation from commercially available 2,3-dichloropyridines and substituted anilines. The combination of a high reaction temperature (180°C) and the use of DBU were found to be crucial for the intramolecular direct arylation reactions of the 3-chloro-N-phenylpyridin-2-amines as no reaction was observed at 120°C and 180°C using different inorganic and other organic bases. On the other hand, nitrogen-methylated pyridine analogues of these substrates {N-[3-chloro-1- methylpyridin-2(1H)-ylidene]anilines} do undergo ring closure at 120°C, with K3PO4 as base, affording the respective 1-methyl-1H-α-carbolines in good yields.
