本发明涉及新型噁唑烷酮(式 I):
或具有以含 N 的单环、双环或螺环取代基为特征的环 A 的药学上可接受的盐,涉及它们的制备,以及它们作为治疗结核分枝杆菌和其他微生物感染的药物的用途,可以单独使用,也可以与其他抗感染治疗药物联合使用。
Nmp-based ionic liquids: Recyclable catalysts for both hetero-Michael addition and Knoevenagel condensation in water
A series of novel N-methyl piperidine (Nmp)-based ionic liquids with 1,2-propanediol group are synthesized and used as catalysts for both hetero-Michael addition of alpha,beta-unsaturated amides and Knoevenagel condensation at room temperature in water; and all the examined substrates could be transformed into corresponding products in good to excellent yields. Meanwhile IL-catalyzed hetero-Michael addition of alpha,beta-unsaturated amides in water has not been reported in the previous literatures. Additionally, the catalyst is recyclable for the two reactions. This finding provides a green catalyst for both hetero-Michael addition of alpha,beta-unsaturated amides and Knoevenagel condensation in water.
Pronounced Catalytic Effect of a Micellar Solution of Sodium Dodecyl Sulfate (SDS) on the Efficient C-S Bond Formation<i>via</i>an Odorless Thia-Michael Addition Reaction through the<i>in situ</i>Generation of<i>S</i>-Alkylisothiouronium Salts
Abstractmagnified imageA pronounced catalytic effect of sodium dodecyl sulfate (SDS) was observed on thein situproduction ofS‐alkylisothiouronium saltsviathe reaction of primary, allyl and benzyl halides with thiourea in SDS droplets .Hydrolysis of the generatedS‐alkylisothiouronium salts in the palisade layer of the droplets produces the corresponding thiol moieties which are immediately added to the electron‐deficient olefins that are present in the micellar core to produce the thia‐Michael adducts. The entire route is an almost odorless process. The yields of the products are good to excellent and the method is applicable to large‐scale operation without any problem.
Thio-Michael addition of α,β-unsaturated amides catalyzed by Nmm-based ionic liquids
A simple and practical thio-Michael addition of α,β-unsaturatedamides catalyzed by Nmm-based ionic liquids with a 1,2-propanediol group has been developed. All the α,β-unsaturatedamides without substituents at the carbon end could smoothly react with sulfur-nucleophiles in water. Meanwhile for thio-Michael addition of α,β-unsaturatedamides with substituents at the carbon end, the relevant product
