Kumar, Gupta Girish published the artcileIsolation of 4-hydroxythiazoline. A solid phase study in Hantzsch thiazole reaction, Computed Properties of 3696-23-9, the publication is Research Journal of Chemistry and Environment (2014), 18(2), 38-44, database is CAplus.
A simple, efficient and rapid practical procedure for the preparation of various thiazole derivatives was developed. The present protocol offered the solid phase reaction of various α-bromo ketones with a wide variety of thioamides/thioureas in the presence of Na2CO3 at room temperature (within 3-5 min). More specifically, it also provided an excellent synthetic route to 2-(pyrazol-1-yl)thiazole derivatives that can not be prepared easily using solvent or acidic conditions mediated Hantzsch thiazole reaction due to the exclusive formation of thiocyanatoketones. Increase in amount of solid catalyst led to the formation of 4-hydroxythiazole, a cyclic intermediate which is formed in Hantzsch thiazole reaction. In conclusion, reaction could be stopped either at intermediate state or was directed towards thiazole formation by changing the amount of base.
