Efficient and regioselective synthesis of phenothiazine via ferric citrate catalyzed C-S/C-N cross-coupling

Efficient C-S and C-N cross-coupling reactions have been developed for regioselective, scalable and environmentally benign synthesis of substituted phenothiazine derivatives. Cross-coupling reactions were demonstrated on various challenging substrates using non-toxic, highly economical, readily available ferric citrate as a catalyst to get desired product with high regioselectivity. Atom economy is the added advantage of this protocol since additional N-protection step before coupling and eventual deprotection of the same to obtain the desired product arenot required. To the best of our knowledge, this is the first report on the use of inexpensive ferric citrate as a catalyst without involving any ligand for the synthesis of regioselectively substituted phenothiazine.

Visible-Light-Promoted Direct Amination of Phenols via Oxidative Cross-Dehydrogenative Coupling Reaction

A transition-metal-free approach was disclosed for intermolecular aryl C-N bonds formation between phenols and cyclic anilines via cross-dehydrogenative coupling (CDC) amination that was mediated by visible light, wherein K2S2O8 served as an external oxidant. The salient features of this protocol include circumventing the requirement for prefunctionalized starting materials and achieving single regioselectivity of amination adducts at room temperature.

Copper-Catalyzed Aerobic Oxidative Amination of Indole Derivatives via Single-Electron Transfer

An efficient and clean approach for the oxidative amination of indole derivatives with phenothiazines is developed under copper-catalyzed aerobic conditions. The reaction is carried out via the cross-coupling of indole radical cation and phenothiazine radical in air. This approach offers a new perspective in the application of phenothiazine as a nitrogen group source for C?N bond formation reactions.

Selective N-alkylation of arylamines with alkyl chloride in ionic liquids: Scope and applications

An efficient N-selective alkylation of primary aromatic amines in molten quaternary ammonium salts, as the solvent, under relatively mild and base-free conditions is presented. On the basis of the Kamlet-Taft parameters and the nucleophilicity of the IL (ionic liquid) anions, the influence of the ionic liquid was evaluated. This protocol was validated on a larger multigram scale and with the syntheses of bioactive heterocycles (e.g., 1,4-benzothiazine and quinoxalines) and new efficient MALDI matrixes. Copyright

Adjunctive application of antimicrobial photodynamic therapy in the prevention of medication-related osteonecrosis of the jaw following dentoalveolar surgery: A case series

Background: Medication-related osteonecrosis of the jaw (MRONJ) is a debilitating complication strongly associated to antiresorptive agents. The present study aimed to describe the use of antimicrobial photodynamic therapy (aPDT) in the prevention of MRONJ. Methods: The sample consisted of 11 non-oncologic osteoporotic subjects in therapy with non-intravenous antiresorptive agents, requiring tooth extractions and/or implant removal. After minimally invasive surgical extractions, each alveolar socket was debrided and bony edges were smoothened. At this point, aPDT was performed using methylene blue-based phenothiazine chloride dye irradiated with a hand-held 100 mW diode laser with a wavelength of 660 ¡À 10 nm. Flaps were sutured to achieve first intention closure. Soft tissue healing was promoted with weekly applications of low-level laser therapy for 6 weeks. Recall visits were scheduled weekly for the first two months and monthly thereafter up to 6 months. At the 6-month appointment, healing was assessed clinically and radiographically. Results: A total of 62 surgical extractions were performed in both jaws, including 51 natural elements and 11 dental implants. No intraoperative complications were observed. Immediate post-operative period was generally uneventful except for mild pain and ecchymosis that occurred rarely and resolved spontaneously. Healing proceeded uneventfully, with no clinical or radiological prodromal manifestations of MRONJ up to the latest follow-up visit. Conclusions: aPDT might constitute a promising preventive treatment to reduce the risk of MRONJ in non-oncologic osteoporotic patients treated with non-intravenous antiresorptive agents that underwent dentoalveolar surgery.

Rearrangement of an aniline linked perylene bisimide under acidic conditions and visible to near-infrared emission from the intramolecular charge-transfer state of its fused derivatives

We have prepared a series of aniline-linked and fused perylene bisimides (PBIs) for making near-infrared (NIR) fluorophores. During this research, we found an unexpected rearrangement reaction on the PBI core for the first time. The aniline- and phenothiazine-fused PBIs exhibit excellent absorption ability and visible-to-NIR emission owing to their intramolecular charge transfer character.

REACTION OF CHLORO DERIVATIVES OF 10-BENZYL- AND 10-(4′-FLUOROBENZYL)PHENOTHIAZINES WITH NITRILES AND AMINES UNDER ARYNE-FORMING CONDITIONS

2-Chloro-10-benzylphenothiazine (1) and 2-chloro-10-(4′-fluorobenzyl)phenothiazine (2) react with aliphatic nitriles (3 and 4) and LDA to yield typical 2-substituted aryne products (9a,b and 9g,h, respectively).However, treatment of 1 with aromatic nitriles (5-8) and LDA supplies 2-(arylmethyl)-1-cyano rearranged nitriles (10c-f), whereas 2, when treated similarly, affords both rearranged nitriles (10i-l) and typical 2-arylated nitrile products (9i-j).An explanation in terms of the effect of substituents on the competing aryne and tandem addition-rearrangement pathways is presented.The crystal structure of one of the rearranged 1-cyanophenothiazines (10c) was obtained and reveals that the molecule adopts the “extra” conformation in which the 10-benzyl group is in the pseudo axial position.The reaction of 1 and 2 with various lithium amides in the corresponding free amine solvents gives the corresponding 2-aminated products (11) and (12) in excellent yields.Both 1-chloro-10-benzylphenothiazine (18) and 1 supply the same product, 10-benzyl-2-N,N-diisopropylaminophenothiazine (11a), when made to react with LDA in diisopropylamine solvent, indicating that each of these reactions proceeds via the same aryne intermediate, and not through the SRN1 mechanism.
