An efficient procedure for the synthesis of 2-aminothiazoles via DBH-mediated oxidative cyclization of styrenes and thioureas is reported. Various alkenes were successfully transformed to the corresponding 2-aminothiazoles in yields of 10–81% via a two-step one-pot manner using DBH as both the bromine source and oxidant. The method can be readily carried out in gram-scale and successfully applied to
A convenient and efficient method is described for the synthesis of 2-aminothiazoles by one-pot reaction of ketone and thiourea using chitosan nanoparticles under mild condition. Nanochitosan was used as a biodegradable and green catalyst for this reaction in satisfactory yields. The attractive advantages of the present process include easy isolation of products, milder and cleaner conditions, higher

Regioselective condensation of α‐tosyloxyacetophenones 1 and N‐substituted thioureas 2 in acidicmedium to give regioisomers 2‐aminothiazoles I and 2‐imino‐2,3‐dihydrothiazoles II is largely influenced by the substituents present on 1 and 2. A mechanism, supported by DFT calculations has been proposed to explain the observed regioselectively.
