Synthesis of benzothiazonine by rhodium-catalyzed denitrogenative transannulation of 1-sulfonyl-1,2,3-triazole and thiochromone

A facile synthesis of multi-functionalized benzothiazonine was achieved by the rhodium-catalyzed denitrogenative annulation of 1-sulfonyl-1,2,3-triazole and thiochromone. In view of the excellent atom economy, broad substrate scope and easy availability of starting materials, the protocol provided an efficient strategy for the construction of mediumN,S-heterocycles.

Cu(I)-Catalyzed Enantioselective Alkynylation of Thiochromones

A highly efficient asymmetric synthesis of chiral thiochromanones is developed via Cu(I)/phosphoramidite catalyzed asymmetric alkynylation of thiochromones under mild reaction conditions. The catalyst system is tolerant of various thiochromone precursors and terminal alkynes. The established asymmetric transformation provides different enatiomeric-enriched thiochromanones with more molecular complexity and enables access to chiral thioflavanones, a subgroup of flavonoid by further functionalization.

Development of conjugate addition of lithium dialkylcuprates to thiochromones: Synthesis of 2-alkylthiochroman-4-ones and additional synthetic applications

Lithium dialkylcuprates undergo conjugate addition to thiochromones to afford 2-alkylthiochroman-4-ones in good yields. This approach provide an efficient and general synthetic approach to privileged sulfur-containing structural motifs and valuable precursors for many pharmaceuticals, starting from common substrates-thiochromones. Good yields of 2-alkyl-substituted thiochroman-4-ones are attained with lithium dialkylcuprates, lithium alkylcyanocuprates or substoichiometric amount of copper salts. The use of commercially available inexpensive alkyllithium reagents will expedite the synthesis of a large library of 2-alkyl substituted thiochroman-4-ones for additional synthetic applications.

Cu-Catalyzed Conjugate Addition of Grignard Reagents to Thiochromones: An Enantioselective Pathway for Accessing 2-Alkylthiochromanones

The enantioselective incorporation of alkyl groups in thiochromones was realized for the first time by a Cu/(R, S)-PPF-P t Bu 2 -catalyzed conjugate addition of Grignard reagents to thiochromones. With this method, a series of 2-methylthiochromanones were obtained in good yields (up to 96% yield) with moderate-to-good ee values (up to 87% ee). The established method expedites the synthesis of a large library of chiral thiochromanones for further synthetic applications and biological studies.

Design, synthesis, and biological evaluation of 4-chloro-2H-thiochromenes featuring nitrogen-containing side chains as potent antifungal agents

A series of 4-chloro-2H-thiochromenes featuring nitrogen-containing side chains were designed, synthesized and tested in vitro for their antifungal activities. The results of preliminary antifungal tests showed that most target compounds exhibited good inhibitory activities against Candida albicans, Cryptococcus neoformans, Candida tropicalis. Notably, compounds 10e and 10y showed most potent activity in vitro against a variety of fungal pathogens with low MICs. Meanwhile, low cytotoxicity on mammalian cells has been observed for compounds 10e and 10y in the tested concentrations by the MTT assay. Therefore, the 4-chloro-2H-thiochromenes with nitrogen-containing groups provide new lead structures in the search for novel antifungal agents.

Microwave-assisted synthesis of novel bisspiropyrrolidine thiochromanone derivatives and antifungal activity

Background: Multicomponent Reactions are being widely used in the synthesis of heterocyclic compounds. Spiroheterocyclic compounds also have various physiological activities such as anti-tumor and antifungal, and they are important in drug discovery. In order to find novel spiroheterocyclic compounds having potential antifungal activity, we found a fast and efficient approach to the synthesis of novel 4′-phenyldispiro[indoline-3,2′-pyrrolidine-3′,3″-thiochromane]-2,4″-dione, and the antifungal activity of the novel spiroheterocyclic compounds were tested. Methods: A variety of different substituents of 3-arylidene-thiochroman-4-one (1mmol) with isatin (1mmol) and different substituted amino acids (sarcosine, proline, leucine, glycine, phenylglycine, alanine, phenylalanine, glutamic acid or arginine, 1mmol) were mixed in [Bmim]Cl (2mL) and then gave microwave irradiation. After the reaction have finished, the reaction system was added in 10mL water, and a lot of white precipitation was obtained and filtrated. The pure objects were recrystallization by mixture of ethanol and water. The antifungal activity was determined by consecutive double dilution method. Results: Microwave irradiation dramatically decreases reaction time from hours to minutes for this multicomponent reaction, and the yields were also slightly increased. Neutral and acidic amino acids can successfully occur 1, 3-dipolar cycloaddition reactions but basic amino acids such as arginine can not. The solvent - [Bmim]Cl can be recycled to reuse after treatment. Compounds 6c and 6d have good inhibition than fluconazole for the two invasive fungi (C.n. and M.r.) and some compounds show moderate inhibition activities for tested fungi. Conclusion: A microwave-enhanced, fast, and efficient three-component reaction in [Bmim]Cl for generation of series novel 4′-phenyldispiro[indoline-3,2′-pyrrolidine-3′,3″-thiochromane]-2,4″-dione compounds has been developed. Among these compounds, several show better anti-invasive fungal activity than fluconazole and some show moderate inhibiton activity.

Rh-Catalyzed Conjugate Addition of Arylzinc Chlorides to Thiochromones: A Highly Enantioselective Pathway for Accessing Chiral Thioflavanones

A highly efficient asymmetric synthesis of chiral thioflavanones is developed via conjugate addition of arylzinc reagents to thiochromones using Rh(COD)Cl2/(R)-3,4,5-MeO-MeOBIPHEP catalyst. This method overcomes catalyst poisoning and substrate inertness and affords a series of chiral thioflavanones (2-arylthiochroman-4-ones) in good yields (up to 91% yield) with excellent ee values (up to 97% ee). The established asymmetric synthesis paves the way for further pharmaceutical studies.

Ionic liquid catalyzed synthesis of 2-(indole-3-yl)-thiochroman-4-ones and their novel antifungal activities

2-(Indole-3-yl)-thiochroman-4-ones were synthesized via ionic liquid and tested for in vitro antifungal activity. The contribution of ionic liquid to Michael addition reaction is significant. Structures of all compounds are elucidated by 1H NMR, 13C NMR and HRMS. Most of these compounds showed better antifungal activity than fluconazole. The results suggest that 2-(indole-3-yl)-thiochroman-4-ones would be efficient antifungal agents.

Facile one-pot synthesis of some novel thiazolylpyrazole derivatives with antifungal activity

A series of novel 1-(4-phenylthiazol-2-yl)-1,4-dihydrothiochroman[ 4,3-c]pyrazole have been prepared by a three-component reaction of thiochromanone-3-carbaldehyde, phenacyl bromide, and thiosemicarbazide. The reaction was in one-pot and did not require any additional catalyst with moderate yields. This method provided several advantages such as environment friendliness and simple work-up procedure. The compounds were assayed for antifungal activity and some of the new compounds can be further utilized as lead compounds.

Synthesis and antifungal activity of some thiazole derivatives

A series of some thiazole derivatives were designed and synthesized. The structure of newly synthesized compounds was characterized by HRMS, 1H NMR and 13C NMR. The synthesized compounds were evaluated against ten species of fungi in vitro by agar cup plate and micro-titration methods, respectively. The results of antifungal screening reveal that among all the compounds screened three compounds showed moderate antifungal activity. The MIC value of 3 h against two fungal strains C. neoformans and C. albicas is 8 μg mL-1 respectively. The MIC value of 3i against two fungal strains C. neoformans and T. mentagrophytes is 8 μg mL-1 and 16 μg mL-1, respectively and 3a against T. mentagrophytes is 16 μg mL-1, the MIC of others are all beyond 32 μg mL-1.
