Uses

Used in Pharmaceutical Industry:
2-(Trifluoromethyl)phenothiazine is used as a key intermediate in the synthesis of antitubercolosis pharmaceuticals for the development of drugs targeting Mycobacterium tuberculosis, the causative agent of tuberculosis. Its trifluoromethyl group and phenothiazine core contribute to the molecule's ability to interact with biological targets and exhibit therapeutic effects against tuberculosis.
Additionally, 2-(Trifluoromethyl)phenothiazine is used as a building block in the synthesis of antiproliferative agents, which are compounds that inhibit cell proliferation. These agents are crucial in the development of treatments for various diseases, including cancer, where controlling cell growth is essential for managing the disease progression. The presence of the trifluoromethyl group in 2-(Trifluoromethyl)phenothiazine may enhance the molecule's bioactivity and selectivity, making it a valuable component in the design of novel antiproliferative drugs.

Combined KOH/BEt3Catalyst for Selective Deaminative Hydroboration of Aromatic Carboxamides for Construction of Luminophores

The selective catalytic C-N bond cleavage of amides into value-added amine products is a desirable but challenging transformation. Molecules containing iminodibenzyl motifs are prevalent in pharmaceutical molecules and functional materials. Here we established a combined KOH/BEt3 catalyst for deaminative hydroboration of acyl-iminodibenzyl derivatives, including nonheterocyclic carboxamides, to the corresponding amines. This novel transition-metal-free methodology was also applied to the construction of Clomipramine and luminophores.

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.

Hydride-catalyzed selectively reductive cleavage of unactivated tertiary amides using hydrosilane

The first hydride-catalyzed reductive cleavage of various unactivated tertiary amides, including the biologically active aryl-phenazine carboxamides and the challenging non-heterocyclic carbonyl functions, using low-cost hydrosilane as a reducing reagent has been developed. The novel catalyst system exhibits high efficiency and exclusive selectivity, providing the desired amines in useful to excellent yields under mild conditions. Overall, this transition metal-free process may offer a versatile alternative to currently employed expensive reducing reagents, high-pressure hydrogen or metal systems for the selective reductive cleavage of amides.

Iron catalytic phenothiazine synthetic method of compound

The invention provides a synthetic method of an iron-catalyzed phenothiazine compound. The synthetic method comprises the following step: in the presence of an iron salt catalyst, a ligand and an alkali, carrying out C-S coupling, C-N coupling and deacylation reaction on raw materials (N-(2-sulfydryl phenyl) acetamide and o-dibromobenzene) at a certain temperature to obtain the phenothiazine compound. The synthetic method provided by the invention is simple in operation, mild in condition, wide in application range, relatively high in yield and short in reaction time and has a good industrial prospect.

This protocol affords an efficient approach for the construction of phenothiazine derivatives without the need of transition-metal catalyst or ligand. A plausible mechanism is proposed.

Synthesis of deuterium-labeled fluphenazine

The propylpiperazine side chain of fluphenazine has been labeled with two, four, and six deuterium atoms by lithium aluminum deuteride reduction of the appropriate ester or imide. The γ-carbon of the propyl group was labeled with two deuterium atoms by reduction of 10- (2-methoxycarbonylethyl)-2-trifluoromethyl-10H-phenothiazine, while four deuterium atoms were incorporated into the piperazine ring by reduction of 10-[3-(3,5-dioxo-1-piperazinyl)propyl]-2-trifluoro-methyl-10H-phenothiazin e. The latter reduction gave the d4-labeled N-deshydroxyethyl metabolite of fluphenazine.
