Thiazoles

2008
This chapter is a review of the scientific literature from 1995 to 2007. In conjunction with the corresponding chapters in CHEC(1984) and CHEC-II(1996), it constitutes a thorough review of the chemistry of thiazoles. Structures discussed include thiazoles, thiazolines, thiazolidines, thiazolium salts, benzothiazoles, and benzothiazolines as well as ...

Complexes of thiazoles. Part IV. Acetamido-thiazoles as ambidentate ligands

Journal of the Chemical Society, Dalton Transactions, 1972
Some complexes of 2-acetamidothiazole and 2-acetamidobenzothiazole with NiII and CuII have been prepared and three types of co-ordination behaviour distinguished on the basis of their i.r. spectra. The organic ligand donor atoms may be (a) carbonyl oxygen and thiazole nitrogen, (b) amide nitrogen and thiazole nitrogen, or (c) carbonyl oxygen, amide ...

Three-component bis-heterocycliation for synthesis of 2-aminobenzo[4,5]thieno[3,2-d]thiazoles

Organic Chemistry Frontiers, 2019
A cooperative base system has been developed for the novel three-component synthesis of 2-aminobenzo[4,5]thieno[3,2-d]thiazoles via bis-heterocyclization of methylketoxime acetates.

Thiazole Derivatives as Potential Chemotherapeutic Agents: Homolytic Arylation of Thiazole with Phenylazotriphenylmethane

Journal of Pharmaceutical Sciences, 1978
The homolytic arylation of thiazole with phenylazotriphenylmethane (as a free radical source) was carried out to explore the potential chemotherapeutic activity of the resulting triphenylmethyl derivatives. The experimental data differed from similar results on other isosteric heterocycles: one compound only was obtained, having both phenyl and ...
