Poly(ethylene glycol) as a reaction matrix in platinum- or gold-catalyzed cycloisomerization: A mechanistic investigation

Abstract

Design for diversity: A new catalytic system based on PEG-3400 and a metal salt (Pt or Au) was designed to efficiently perform a cycloisomerization reaction under microwave irradiation, which gave diverse heterocycles in good to excellent yields, after a precipitation/filtration procedure (see scheme).
