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.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 1532-97-4

Distortions of a flexible metal-organic framework from substituted pendant ligands

Four new variants of the 1,4-benzenedicarboxylate MIL-53 structure have been prepared for CoII under solvothermal conditions and their structures solved and refined from single-crystal X-ray data. All materials contain pendant pyridine-N-oxide ligands that bridge pairs of CoII atoms in the inorganic backbone of the structure via O. By the use of the ligands 3-bromopyridine-N-oxide, 4-methoxypyridine-N-oxide, isoquinoline-N-oxide and 4-phenylpyridine-N-oxide, materials are prepared with the same topology but distinct structures. These illustrate how the MIL-53 structure is able to distort to accommodate the bulk of the various substituents on the pyridine ring. The bulkiest pendant ligand, 4-phenylpyridine-N-oxide, results in a distortion of the diamond-shaped channels in an opposite sense to that seen previously in expanded forms of the parent MIL-53 structure. By comparison with published crystal structures for MIL-53 with various occluded guests, the structural distortions that take place to accommodate the pendant ligands are quantified and it is shown how a twisting of the 1,4-benzenedicarboxylate ligand, instead of a hinging about the mu2-carboxylate-metal connection, allows the new structures that are observed.

Homoleptic Cyclometalated Iridium Complexes with Highly Efficient Red Phosphorescence and Application to Organic Light-Emitting Diode

Phosphorescence studies of a series of facial homoleptic cyclometalated iridium(III) complexes have been carried out. The complexes studied have the general structure Ir(III)(C-N)3, where (C-N) is a monoanionic cyclometalating ligand: 2-(5-methylthiophen-2-yl)pyridinato, 2-(thiophen-2-yl)-5-trifluoromethylpyridinato, 2,5-di(thiophen-2-yl)pyridinato, 2,5-di(5-methylthiophen-2-yl)pyridinato, 2-(benzo[b]thiophen-2-yl)pyridinato, 2-(9,9-dimethyl-9H-fluoren-2-yl)pyridinato, 1-phenylisoquinolinato, 1-(thiophen-2yl)isoquinolinato, or 1-(9,9-dimethyl-9H-fluoren-2-yl)isoquinolinato. Luminescence properties of all the complexes at 298 K in toluene are as follows: quantum yields of phosphorescence phip = 0.08-0.29, emission peaks lambda max = 558-652 nm, and emission lifetimes tau = 0.74-4.7 mus. Bathochromic shifts of the Ir(thpy)3 family [the complexes with 2-(thiophen-2-yl)pyridine derivatives] are observed by introducing appropriate substituents, e.g., methyl, trifluoromethyl, or thiophen-2-yl. However, phip of the red emissive complexes (lambdamax > 600 nm) becomes small, caused by a significant decrease of the radiative rate constant, kr. In contrast, the complexes with the 1-arylisoquinoline ligands are found to have marked red shifts of lambdamax and very high phip (0.19-0.26). These complexes are found to possess dominantly 3MLCT (metal-to-ligand charge transfer) excited states and have kr values approximately 1 order of magnitude larger than those of the Ir(thpy)3 family. An organic light-emitting diode (OLED) device that uses Ir(1-phenylisoquinolinato)3 as a phosphorescent dopant produces very high efficiency (external quantum efficiency etaex = 10.3% and power efficiency 8.0 Im/W at 100 cd/m2) and pure-red emission with 1931 CIE (Commission Internationale de L’Eclairage) chromaticity coordinates (x = 0.68, y = 0.32).

Copper-Mediated Oxidative Functionalization of C(sp3)-H Bonds with Isoquinolines: Two-Step Synthesis of 5-Oxaprotoberberinones

A copper-mediated oxidative functionalization of C(sp3)-H bonds with isoquinolines via a radical process without ligands was achieved.

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.

Application of Imine Reductases (IREDs) in Micro-Aqueous Reaction Systems

Here we present the applicability of different imine reductases (IREDs) in micro-aqueous reaction systems. Subjects of the study were the IREDs from Streptomyces aurantiacus (SaIR), Streptomyces sp. GF3587 (RGF3587IR), Streptomyces kanamyceticus (SkIR), Streptomyces ipomoeae 91-03 (SiIR), Streptomyces sp. GF3546 (SGF3546IR), and Paenibacillus elgii B69 (PeIR). The IREDs were overexpressed in Escherichia coli (E. coli) cells and used directly after lyophilization. Several organic solvents and buffer amounts were screened for the reduction of the two substrates beta-carboline harmane and 1-methyl-3,4-dihydroisoquinoline to the corresponding amines. Cyclopentyl methyl ether (CPME) proved to be the best solvent choice for the envisaged reduction. In addition, CPME is currently referred to as an environmentally benign solvent. Optimized reaction conditions were applied to 20 mM of the hardly water soluble substrates, leading to good conversions (up to 96%) and excellent enantiomeric excesses (>99%) in the best cases. The use of micro-aqueous reaction systems opens the way to further applications of IREDs with hardly water soluble substrates. (Figure presented.).

External-Photocatalyst-Free Visible-Light-Mediated Synthesis of Indolizines

A visible-light-mediated synthesis of valuable polycyclic indolizine heterocycles from easily accessed brominated pyridine and enol carbamate derivatives has been developed. This process, which operates at room temperature under irradiation from readily available light sources, does not require the addition of an external photocatalyst. Instead, an investigation into the reaction mechanism indicates that the indolizine products themselves may be in some way involved in mediating and accelerating their own formation. Preliminary studies also show that these simple heterocyclic compounds may be capable of facilitating other visible-light-mediated transformations.
