A concise and straightforward total synthetic approach towards lycorine-type alkaloid (-)-gamma-lycorane has been achieved in 7 steps. The key feature of the route is the employment of a palladium-catalyzed aromatic C-H alkylation of unactivated secondary alkyl iodide. The synthetic protocols also involve a palladium-catalyzed deracemization of allylic carbonate, a Johnson-Claisen rearrangement and an iodocyclization. (C) 2020 Elsevier Ltd. All rights reserved.

A palladium(II)-catalyzed 1,1-difunctionalization of unactivated terminal and internal alkenes via addition of two nucleophiles was developed using a cationic palladium(II) complex. The palladacycle generated in situ as a result of a regioselective addition of a nucleophile to the alkene can readily undergo regioselective beta-hydride elimination and migratory insertion with a cationic palladium catalyst. The resulting eta(3)-pi-allyl palladium(II) complex is the key intermediate that reacts with a second nucleophile to furnish the desired 1,1-difunctionalization of the alkene. Under the optimized reaction conditions, a wide range of indoles and anilines add to alkene units of 3-butenoic or 4-pentenoic acid derivatives to afford the synthetically useful gamma,gamma- or delta,delta-difunctionalized products with excellent regiocontrol. Furthermore, by employing internal hydroxyl or acid groups and external carbon nucleophiles, this transformation enables unsymmetric 1,1-difunctionalization to forge challenging and important oxo quaternary carbon centers. Combining experiments and DFT calculations on the mechanism of the reaction is investigated in detail.

Three iridium(III) complexes (Ir(4tfmpq)(2)mND, Ir(4tfmpq())2mmND, and Ir(4tfmpq)2mpND) with the 4-(4-(trifluoromethyl)phenyl)quinazoline (4tfmpq) main ligand and 1,5-naphthyridin-4-ol derivatives (mND: 8-methy1-1,5-naphthyridin-4-ol, mmND: 2,8-dimethy1-1,5-naphthyridin-4-ol, mpND: 8-methy1-2-pheny1-1,5-naphth-yridin-4-ol) as ancillary ligands were studied. The complexes (Ir(4tfmpq)(2)mND, Ir(4tfmpq)(2)mmND, and Ir(4tfmpq())2mpND) emit pure red emissions of 626-630 nm with high photoluminescence quantum yields of 85.2-93.4% in CH2Cl2 and better electron mobilities than that of tri(8-hydroxyquinoline)aluminum. By employing three pure red emitters, all the phosphorescent organic light-emitting diodes exhibited superior performances with a maximum external quantum efficiency of 31.48% and the efficiency roll-off is very mild, which are among the best results ever reported for pure red organic light-emitting diodes using Ir(III) complexes. In addition, CIE(x, y) coordinates of (0.670, 0.327) are also close to the standard red emission required by the National Television System Committee.

Category: thiazolidines. Annor-Gyamfi, JK; Bunce, RA in [Annor-Gyamfi, Joel K.; Bunce, Richard A.] Oklahoma State Univ, Dept Chem, Stillwater, OK 74078 USA published 4H-Benzo[d][1,3]oxazin-4-ones and Dihydro Analogs from Substituted Anthranilic Acids and Orthoesters in 2019.0, Cited 18.0. The Name is 1,1,1-Triethoxyethane. Through research, I have a further understanding and discovery of 78-39-7.

A one-pot route to 2-alkyl and 2-aryl-4H-benzo[d][1,3]oxazin-4-ones (also known as 4H-3,1-benzoxazin-4-ones) has been developed and studied. The method involves the reaction of aryl-substituted anthranilic acids with orthoesters in ethanol catalyzed by acetic acid. Additionally, we have also investigated the reaction under microwave conditions. Not all of the substrates were successful in yielding the target heterocycles as some of the reactions failed to undergo the final elimination. This process led to the isolation of (+/-)-2-alkyl/aryl-2-ethoxy-1,2-dihydro-4H-benzo[d][1,3]oxazin-4-ones. The formation of the dihydro analogs correlated with the electron density on the aromatic ring: Electron-donating groups favored the 4H- benzo[d][1,3]oxazin-4-ones, while electron-withdrawing groups tended to favor the dihydro product. Substituting a pyridine ring for the benzene ring in the substrate acid suppressed the reaction.

In search for new molecular entities as anti-TB agents, the benzimidazoquinazoline polyheterocyclic scaffold has been designed adopting the scaffold hopping strategy. Thirty-two compounds have been synthesized through an improved tandem decarboxylative nucleophilic addition cyclocondensation reaction of o-phenylenediamine with isatoic anhydride followed by further cyclocondensation of the intermediately formed 2-(o-aminoaryl) benzimidazole with trialkyl orthoformate/acetate. The resultant benzimidazoquinazolines were evaluated in vitro for anti-TB activity against M. tuberculosis H37Rv (ATCC27294 strain). Fourteen compounds exhibiting MIC values in the range of 0.4-6.25 mu g/mL were subjected to cell viability test against RAW 264.7 cell lines and were found to be non-toxic (< 30% inhibition at 50 mu g/mL). The active compounds were further evaluated against INH resistant Mtb strains. The most active compound 6x [MIC (H37Rv) of 0.4 mu g/mL] and the compound 6d [MIC (H37Rv) of 0.78 mu g/mL] were also found to be active against INH resistant Mtb strain with MIC values of 12.5 and 0.78 mu g/mL, respectively.

The first total synthesis of a marine natural product, exigurin, has been accomplished in 13 steps starting from (+)-menthone. The key intermediate (-)-10-epi-axisonitrile-3 was prepared by stereoselective intramolecular cyclopropanation followed by a cyclopropane ring opening reaction by the azide anion. The bioinspired Ugi reaction of (-)-10-epi-axisonitrile-3, formaldehyde, sarcosine and methanol successfully constructed the target exigurin in which its terpene and amino acid units were linked through an amide bond.
