Several straightforward and practical processes have been established for the construction of 2-aminothiazoles, 1,3-thiazoles and 1,3-selenazoles from aryliodoazides. These strategies successfully proceed with a wide spectrum of substituted thioamides and its derivatives producing the resulting five-membered heterocycles obtained in satisfactory yields. The unique features of these protocols are operational
In this paper, the [3 + 2] cycloaddition reaction of thiobenzoyl group derivatives with sulfoxonium ylide was studied, which can directly synthesize 2,4-diarylthiazoles with different structures. Compared with the traditional reaction of producing thiazole, using palladium catalysts is able to make the reaction milder and lower in cost. Thus, a group of 2,4-diarylthiazoles can be easily synthesized
The lipase-catalyzed, ultrasound-assisted synthesis presented in this study represents a greener and more sustainable alternative to traditional synthetic pathways for these important compounds, offering promising potential for applications in medicinal chemistry and drug development. This approach holds the promise of advancing the field of thiazole synthesis, contributing to more sustainable and efficient
A simple construction for various 2,4-disubstituted thiazoles via palladium(II)-catalyzed C(sp)–C(sp2) and C-N cascade couplingreactions was developed. Various substrates can be tolerated with good yields. And its ligand-free condition demonstrates the practicability of this method.
