Continuous-flow synthesis of biaryls enabled by multistep solid-handling in a lithiation/borylation/Suzuki-Miyaura cross-coupling sequence

Let it flow: An efficient and modular synthesis of biaryls under continuous-flow conditions has been realized by a lithiation/borylation/Suzuki- Miyaura cross-coupling sequence under ambient conditions. Aryl bromides and heteroaromatic precursors can be transformed in the room-temperature lithiation reaction with nBuLi, followed by borylation and Suzuki-Miyaura coupling with the aid of ultrasonic irradiation (see scheme).

Palladium-catalysed amination of halopyridines on a KF-alumina surface

Palladium-catalysed C-N hetero cross-coupling reactions between bromopyridines and amines (both primary and secondary) can be efficiently performed on a KF-alumina (basic) surface, thus negating the use of strong bases such as sodium tert-butoxide. The reaction conditions are optimised with reference to catalytic systems, solvents and the surface.

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.HPLC of Formula: C9H6BrN, you can also check out more blogs about1532-97-4

Nano palladium supported on high-surface-area metal-organic framework MIL-101: An efficient catalyst for Sonogashira coupling of aryl and heteroaryl bromides with alkynes

Palladium nanoparticle-incorporated metal-organic framework MIL-101 (Pd/MIL-101) was successfully synthesized and characterized using X-ray diffraction, nitrogen physisorption, X-ray photoelectron, UV-visible and infrared spectroscopies, and transmission electron microscopy. The characterization techniques confirmed high porosity and high surface area of MIL-101 and high stability of nano-size palladium particles. Pd/MIL-101 nanocomposite was investigated for the Sonogashira cross-coupling reaction of aryl and heteroaryl bromides with various alkynes under copper-free conditions. The reusability of the catalyst was tested for up to four cycles without any significant loss in catalytic activity.

NaBH4-TMEDA and a palladium catalyst as efficient regio- and chemoselective system for the hydrodehalogenation of halogenated heterocycles

The pair NaBH4-TMEDA as hydride source and a palladium catalyst in THF prove to be an efficient system for the hydrodehalogenation of halogenated heterocycles with one or more heteroatoms. In general, Pd(OAc) 2-PPh3 rapidly hydrodehalogenates reactive halo-heterocycles such as bromo-pyridines, -quinolines, -thiophenes, -indoles, -imidazoles, etc., at room temperature in very good yields, whereas in most cases PdCl2(dppf) reduces less reactive halides such as chloro-pyridines, -quinolines, -pyrimidines and bromo-indoles, -benzofurans, etc. Moreover, PdCl2(tbpf) shows to be even more active removing the 2- and 5-chlorine from both thiophene and thiazole rings. The reaction conditions tolerate various functional groups, allowing highly chemoselective reactions in the presence of halide, ester, alkyne, alkene and nitrile substituents. Moreover, with a proper selection of the catalyst it is also possible to obtain a good control in the regioselective hydrodehalogenation of a variety of polyhalogenated substrates.

Copper-catalyzed cyanation of heteroaryl bromides: A novel and versatile catalyst system inspired by nature

An improved copper catalyst system for the cyanation of heteroaryl halides leading to substituted heteroaryl nitriles is described. The catalyst system consists of simple CuI and N-alkylimidazoles, and mimics known Cu-containing metalloproteins. It is stable, commercially available, cheap and easily tunable. By using inexpensive and non-toxic K4[Fe(CN)6] and the novel Cu catalysts we were able to cyanate both activated and non-activated heteroarenes with high yield and selectivity. The generality of the procedure is demonstrated by a variety of different examples, some of which did not react under other known methods. Georg Thieme Verlag Stuttgart.

Design, synthesis, and evaluation of novel porcupine inhibitors featuring a fused 3-ring system based on the ?reversed? amide scaffold

The Wnt signaling pathway is an essential signal transduction pathway which leads to the regulation of cellular processes such as proliferation, differentiation and migration. Aberrant Wnt signaling is known to have an association with multiple cancers. Porcupine is an enzyme that catalyses the addition of palmitoleate to a serine residue in Wnt proteins, a process which is required for the secretion of Wnt proteins. Here we report the synthesis and structure?activity-relationship of the novel porcupine inhibitors based on a ?reversed? amide scaffold. The leading compound 53 was as potent as the clinical compound LGK974 in a cell based STF reporter gene assay. Compound 53 potently inhibited the secretion of Wnt3A, therefore was confirmed to be a porcupine inhibitor. Furthermore, compound 53 showed excellent chemical and plasma stabilities. However, the clearance of compound 53 in liver microsomal tests was moderate to high, and the solubility of compound 53 was suboptimal. Collective efforts toward further optimization of this novel tricyclic template to develop better porcupine inhibitors will be subsequently undertaken and reported in due course.

Acetylene-free synthesis of vinyloxy pyridine and quinoline

Copper-catalyzed vinylation of 2- and 4-hydroxy pyridine and quinoline affords exclusively N-vinylation products. However, vinyl ethers of 4-hydroxy pyridine and quinoline can be prepared via a three-step sequence involving copper-catalyzed C-O cross coupling reaction of the corresponding N-heteroaryl bromides with ethylene glycol, chlorination of the terminal alcohol, and dehydrohalogenation of the beta-chloro ethers. Although not efficient in 2-hydroxy series, this method can be conveniently applied to the preparation of various aza-aryl vinyl ethers in moderate to good overall yields.

Allylboration of functionalized isoquinolines

Functionalized isoquinolines react with triallylborane to produce 1,3-diallylated 1,2,3,4-tetrahydroisoquinolines 1-8 with excellent chemo- and stereoselectivity. In these conditions 4-bromoisoquinoline was converted into tricyclic aziridine 10. Synthesis of monoallylated tetrahydroisoquinolines using allyldipropylborane and reduction with NaBH4 was also developed.
