identified as potent inhibitors of 5-lipoxygenase in vitro exhibiting IC50's of less than 1 microM. An investigation of structure-activity relationships showed that the most potent inhibitors of this series are the 5-phenyl derivatives. The corresponding thiazolidin-4-one analogues were found to be relatively inactive. The 4-hydroxythiazoles were active inhibitors against 5-lipoxygenase in both intact rat
An inverse-electron-demand oxa-Diels–Alder reaction of 5-alkenyl thiazolones with β,γ-unsaturated carbonyl compounds enabled by quinine thiourea was studied, which allows the enantioselective synthesis of a broad range of highly functionalized pyranthiazoles bearing three continuous stereocenters. This protocol is adaptable to a wide scope of substrates and has great potential for scale-up synthesis
We have developed an organocatalyzedasymmetric three‐component reaction of thiazol‐4‐ones, acrolein and nitroolefins, which provides an efficient approach to access optically active spiro thiazol‐4‐ones. Under the catalysis of a bifunctional squaramide derived from L‐tert‐leucine, the reactions of a wide range of thiazol‐4‐ones, acrolein and nitroolefins took place smoothly to generate the corresponding
