supporting information, p. 986 - 990 (2019/03/12)
Multi-component reactions for the synthesis of polysubstituted thiazoles from simple chemicals are described. Under metal-free reaction conditions, cheap and easily available ketones, aldehydes, ammonium salt, and elemental sulfur are self-assembled to provide entries to three thiazoles in moderate to good yield with a range of functionalities tolerated.

experimental part, p. 3161 - 3163 (2009/08/07)
The nucleophilic substitution reactions of vinylic bromides with intramolecular thioamide or thiourea moieties proceed to give a series of substituted thiazoles and imidazole-2-thiones.
1,3-dipolar cycloadditions with 1-alkoxy-substituted nitrile ylides

Thermolysis of 4-alkoxy-1,3-oxazol-5(2H)-ones (2) (X = O) leads to reactive nitrile ylides (1) bearing an alkoxy substituent at the nitrile C-atom. These intermediates can be trapped by C,C-, C,O-, C,N-, and C,S-dipolarophiles, yielding 5-membered heterocycles via 1,3-dipolar cycloaddition. In the case of 1,3-thiazole-5(4H)-thiones (11) as dipolarophiles, two regioisomeric cycloadducts were obtained. The results of the cycloadditions are discussed with respect to the influence of the alkoxy substituent on the structure of the nitrile ylide.
