“…PEG and its monoethyl ethers are inexpensive, thermally stable, reusable, and non-toxic media and are also phase-transfer catalysts. 118 have been carried out and investigated in PEG. It has also been reported by a few researchers that PEG-mediated synthesis to prepare aminothiazoles is efficient and green method.…”

Aminothiazoles and their derivatives are of immense biological importance and have been consistently synthesized via various methods. However, the synthesis of aminothiazole derivatives has some problems such as poor yields, difficult isolation procedures, use of expensive catalysts etc. Recently, polymer or solid-supported synthetic protocols have attracted the attention from the research community because of their easy execution, increased product yields, greater selectivity, simple work-up procedures, and recoverability of the catalysts. In this study, we reported the polymer-supported approaches for the synthesis of differently substituted aminothiazoles.

“…Furthermore, the cost of ionic liquids is often more expensive than that of PEG. 15 To date some of the more important reactions have been carried out and investigated in PEG, for example, Heck reaction, 16 catalytic hydrogenations, 17 asymmetric dihydroxylation reaction, 18 Baylis-Hillman reaction, 19 Biginelli reaction, 20 SuzukiMiyaura reaction, Stille cross-coupling reaction, 21 Wacker reaction, 22 and asymmetric aldol reaction, 23 etc.…”
