Stereoselective synthesis of 1,3-disubstituted dihydroisoquinolines vial-phenylalanine-derived dihydroisoquinoline N-oxides

The preparation of chiral pool-derived nitrone 3 and its use in the protecting-group free, stereoselective synthesis of a range of 1,3-disubstituted tetrahydroisoquinolines is described. Grignard reagent additions to nitrone 3 yielded trans-1,3-disubstituted N-hydroxytetrahydroisoquinolines 6 with good levels of selectivity, while 1,3-dipolar cycloadditions to this nitrone provided access to 3-(2-hydroxyalkyl)isoquinolines 12 as single diastereomers.

Pure red electrophosphorescence from polymer light-emitting diodes doped with highly emissive bis-cyclometalated iridium(III) complexes

In order to develop highly emissive red phosphorescent materials for OLED application, novel bis-cyclometalated iridium(III) complexes were developed using the 1-(dibenzo[b,d]furan-4-yl)isoquinolinato-N,C3? (dbfiq) cyclometalating ligand. When 1,3-bis(3,4-dibutoxyphenyl)propane-1,3- dionate (bdbp) is employed as an ancillary ligand, Ir(dbfiq)2(bdbp) 1 exhibits red photoluminescence (PL) at 640 nm with a quantum yield (PhiPL) of 0.61 (in toluene, 298 K). Replacement of bdbp to dipivaloylmethanate (dpm) and acetylacetonate (acac) (Ir(dbfiq)2(dpm) 2 and Ir(dbfiq)2(acac) 3, respectively) does not affect the PL spectrum, but reduces PhiPL to 0.55 and 0.49 for 2 and 3, respectively. Similar tendency is also found in the doped poly(methyl methacrylate) (PMMA) film, and 1 is more emissive (PhiPL = 0.17) than 2 and 3 (PhiPL = 0.08 and 0.06, respectively). Using 1 as a phosphorescent dopant, polymer light-emitting diodes (PLEDs) were fabricated, of which structure was ITO/PEDOT:PSS (40 nm)/PVCz:1:PBD (100 nm)/CsF (1 nm)/Al (250 nm). Pure red electroluminescence (EL) is obtained from the fabricated PLEDs, affording a CIE chromaticity coordinate of (0.68, 0.31). When 0.51 mol% of 1 is incorporated in the PVCz-based emitting layer, the PLED shows maximum luminance of 7270 cd m-2 at 16.5 V, power efficiency of 1.4 lm W -1 at 7.5 V, and external quantum efficiency of 6.4% at 9.0 V. PLEDs with the same structure and components were also fabricated using 2 and 3, and their device characteristics were investigated. In proportion to the PL quantum yields, 1 affords better device performance than 2 and 3. Owing to four butoxy groups introduced to the bdbp ligand, 1 exhibits high solubility in organic solvents such as chloroform and toluene, and thus, is an excellent red phosphorescent dopant for solution-processed OLEDs. A highly emissive red phosphorescent bis-cyclometalated iridium(III) complex, bis[1-(dibenzo[b,d] furan-4-yl)isoquinolinato-N,C3?]iridium(III) [1,3-bis(3,4-dibutoxyphenyl)propane-1,3-dionate-O,O] 1 was developed. It exhibits red photoluminescence with PhiPL of 0.61 (toluene, 298 K). The electrophosphorescence from the polymer light-emitting diode containing 1 affords a CIE chromaticity coordinate of (0.68, 0.31) shifting to pure red over the NTSC standard.

Photochemistry of Methoxy-substituted Quinoline and Isoquinoline N-Oxides

The photochemistry of quinoline 1-oxides and isoquinoline 2-oxides bearing a methoxy-group in the pyridine ring was investigated in protic and aprotic media.The formation of various photoisomers, viz. 3,1-benzoxazepines, 2(1H)-quinolones, N-(2-isocyanobenzyl)formamides, 4(1H)-quinolones, and 3-hydroxyquinolines from the different methoxyquinoline 1-oxides, and 1,3-benzoxazepines and 1(2H)-isoquinolones from the different methoxyisoquinoline 2-oxides, was observed along with deoxygenation and formation of products derived from hydration and decomposition of the primary products.The position of the methoxy-group has an important directing effect on the photoreactions.

A general and efficient catalyst for palladium-catalyzed C-O coupling reactions of aryl halides with primary alcohols

An efficient procedure for palladium-catalyzed coupling reactions of (hetero)aryl bromides and chlorides with primary aliphatic alcohols has been developed. Key to the success is the synthesis and exploitation of the novel bulky di-1-adamantyl-substituted bipyrazolylphosphine ligand L6. Reaction of aryl halides including activated, nonactivated, and (hetero)aryl bromides as well as aryl chlorides with primary alcohols gave the corresponding alkyl aryl ethers in high yield. Noteworthy, functionalizations of primary alcohols in the presence of secondary and tertiary alcohols proceed with excellent regioselectivity.

Chemoselective chromium(II)-catalyzed cross-coupling reactions of dichlorinated heteroaromatics with functionalized aryl Grignard reagents

Chromium(II) chloride catalyzes the chemoselective cross-coupling reaction of dichloropyridines with a range of functionalized (hetero)aromatic Grignard reagents at room temperature. Functional groups, such as esters and acetals, are well tolerated in this transformation. Previously challenging substrates, quinolines and isoquinolines, participate in the selective Cr-catalyzed cross-coupling in cyclopentyl methyl ether (CPME) as the solvent. The effective purging of Cr salts is demonstrated by using various solid supports.
