An efficient synthesis of the potent dopamine D1 agonist dinapsoline by construction and selective reduction of 2?-azadimethoxybenzanthrone

8,9-Dihydroxy-2,3,7,11b-tetrahydro-1H-naphth[1,2,3-de]isoquinoline (dinapsoline, 1) is a potent dopamine D1 receptor agonist with potential antiparkinsonian activity. A new synthesis was developed with the fully aromatic compound 2 as the key intermediate. The synthesis herein described is suitable for a larger scale preparation of dinapsoline compared to the previously known methods. Furthermore, the unproductive protection/deprotection step of the nitrogen is circumvented by maintaining a high oxidation state of the isoquinoline moiety throughout the synthesis. The construction of the framework was accomplished by Friedel-Crafts acylation and a Suzuki cross-coupling reaction between the commercially available 4-bromoisoquinoline and aryl boronic acid 5, the latter demanding the transformation of the lithiation-directing amide back to a carboxylic acid functionality. The selective reduction was carried out stepwise with sodium borohydride and sodium cyanoborohydride. The new synthesis is high yielding and reduces the number of transformations in the previously reported methods.

Cesium carbonate-promoted synthesis of aryl methyl sulfides using: S -methylisothiourea sulfate under transition-metal-free conditions

In the presence of cesium carbonate, an efficient synthesis of aryl methyl sulfides by the reactions of aryl halides with commercially available S-methylisothiourea sulfate is developed. This odourless and highly crystalline solid can be used as the substitute for malodorous methanethiol. The gram-scale reaction also proceeds smoothly without the use of column chromatography separation. Similarly, 2-(dimethylamino)ethylthio and cyclopropylmethylthio groups can be easily introduced into the aromatic rings from the corresponding S-[2-(dimethylamino)ethyl]isothiourea dihydrochloride and S-cyclopropylmethylisothiourea hydrobromide. The possible reaction mechanism is proposed. It is believed that this route to aryl alkyl sulfides is well competitive with currently known methods due to its wide substrate scope, excellent yields, easy operation and transition-metal-free conditions.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Visible Light-Mediated Direct Decarboxylative C-H Functionalization of Heteroarenes

The direct visible light-mediated C-H alkylation of heteroarenes using aliphatic carboxylic acids is reported. This mild method proceeds at low catalyst loadings (0.5 mol %) and has a high functional group tolerance and a broad substrate scope. Notably, functionalization of (iso)quinoline, pyridine, phthalazine, benzothiazole, and other heterocyclic derivatives with both cyclic and acyclic primary, secondary, and tertiary carboxylic acids as well as amino and fatty acids proceeded under the standard conditions at room temperature. This protocol enables the rapid conversion of abundant feedstock materials into medically relevant “drug-like” moieties.

Luminescent Pt(ii) complexes bearing dual isoquinolinyl pyrazolates: Fundamentals and applications

A series of four Pt(ii) metal complexes with trans-arranged isoquinolinyl azolates have been prepared, [Pt(Lx)2], x = 1-4, (1-4). The associated chelates possess various substituents; namely: one t-butyl (But) at the 6-position (L1), two But groups at the 5,7-positions (L2), one dip (2,6-di-isopropylphenyl) group at the 6-position (L3), and a single dip group at the 4-position of the 1-isoquinolinyl fragment (L4), respectively. Crystal structures of 1 and 4 were determined to shed light on the relationship of photophysics and packing arrangements. Their photophysical properties were measured and compared, for which the solid-state emission spectra of 2 and 4 are nearly identical to the solution spectra of all the Pt(ii) complexes, showing the formation of isolated molecular entities. In contrast, the Pt(ii) complexes 1 and 3 are found to be sensitive to their morphological states and external stimulus. This is confirmed by the gradual red-shifting of the emission with increasing concentration in the PMMA matrix, and the eventual formation of the broadened, metal-metal-to-ligand charge transfer (MMLCT) emission, by (i) wetting with acetone and drying in air, or (ii) grinding with a mortar and pestle, respectively. Organic light-emitting diodes (OLEDs) were also fabricated using multiple layered architecture and lowered doping concentration (e.g. 8 wt%), the latter is for avoiding dopant aggregation in the emitting layer. The associated OLED performances (i.e. etamax = 11.5%, 8.5%, and 11.2% for 1, 2 and 3) confirmed their suitability and potential as dopants for phosphorescent OLEDs.

Palladium catalyzed direct 3-arylation of benzofurans using low catalyst loadings

The palladium-catalyzed direct 3-arylation of benzofurans provides a cost-effective and environmentally attractive route for the preparation of 3-arylbenzofuran derivatives. The reactions were carried out using a wide variety of electronically and sterically diverse aryl or heteroaryl bromides with low catalyst loadings. In the presence of only 0.1-0.5 mol% catalyst, products in moderate to good yields were obtained. The aryl bromide reactants were able to tolerate a wide range of functionalities, such as acetyl, propionyl, formyl, ester, nitrile, trifluoromethyl, or fluoro groups. Higher yields were obtained using electron-deficient aryl bromides as reactants compared to using electron-rich aryl bromides. Functionalized benzofuran derivatives, bearing formyl or hydroxymethyl on C2, were also successfully employed.
