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. The present system exhibits a novel pathway for the preparation of N-alkyl (benzyl) isoquinolin-1(2H)-ones in moderate to high yields. In addition, this procedure provides a simple method to afford 5-oxaprotoberberinones and their derivatives in two steps.

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).

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.

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.

Synthesis of 2-thio-substituted benzothiazoles via a domino condensation/S -arylation/heterocyclization process

Condensation of carbon disulfide with thiols in the presence of K 2CO3 generates carbonotrithioate salts in situ, which undergo coupling with 2-iodoanilines and subsequent intramolecular condensation and elimination under assistance of CuBr to afford 2-thio-substituted benzothiazoles. Both aliphatic and aromatic thiols are compatible with this process, delivering the corresponding heterocycles with good diversity.

Synthesis of Isoquinolines from Indenes

A general procedure for the synthesis of isoquinolines from appropriately substituted indenes is described.Ozonolysis of the indenes followed by reductive workup gives intermediate homophthalaldehydes which are treated with ammonium hydroxide to give the isoquinolines.This “one-pot”, three-step reaction sequence was applied to the formation of all of the mono-C-methyl-substituted isoquinolines in a regiospecific manner.The procedure is applicable to both electron-withdrawing and electron-donating substituents on the indene system.In this manner the 6- and 7-nitro-,-bromo-, and -iodoisoquinolines were prepared.
