Synthetic method of 4,5-disubstituted-2-aminothiazole compound

The invention discloses a synthetic method of a 4,5-disubstituted-2-aminothiazole compound. The synthetic method sequentially comprises the following steps: 1) making a nitro-epoxy compound react withammonium thiocyanate in the presence of a solvent and an alkali catalyst at the temperature of 40-/+5 DEG C for 10 to 14 hours; 2) adding water into reaction liquid prepared in the step 1), extracting the mixture with ethyl acetate, washing a prepared organic layer, drying the organic layer, and performing concentration with a rotary evaporator; 3) performing silica gel column chromatography on the concentrate prepared in the step 2) to obtain the 4,5-disubstituted-2-aminothiazole compound. The method for synthesizing the 4,5-disubstituted-2-aminothiazole compound disclosed by the invention has the characteristics of adoption of readily-available raw materials, mild reaction conditions, high yield, convenience in post treatment and the like.

Efficient and facile strategy to substituted 2-aminothiazoles via ring opening of α-nitroepoxides

A novel and efficient reaction has been developed to synthesize a set of substituted 2-aminothiazoles from α-nitroepoxides and ammonium thiocyanate. This reaction could proceed smoothly at mild condition, to afford products for a wide range of substrates with good to excellent yields. A possible mechanism has also been proposed.

One-pot three-component protocol for the synthesis of substituted 2-aminothiazoles

Substituted 2-aminothiazoles have been synthesized from α-nitro-epoxides, cyanamide, and sodium sulfide through a facile, three-component, and ecofriendly protocol with good to excellent yields. This reaction was achieved at room temperature without any additives. A possible mechanism has also been proposed.

Synthesis of 5-Phenylthiazolamines by Using Thiourea as an α-Bromination Shuttle

A straightforward synthesis of 5-phenylthiazolamines by coupling thiourea with phenylacetones, phenylacetophenones, and β-tetralone has been developed. Thiourea acts as a substrate and an α-bromination shuttle by transferring a Br atom from CBrCl3/s
