This review is a survey of the literature describing synthetic applications of oxime ethers. The cyclization and metal-catalyzed cross-coupling reactions of oxime ethers in recent years are also highlighted.
In this study, for the first time, calix[4]resorcinarene was grafted on the silica-coated magnetic nanoparticles (MNPs-Si) which efficiently catalyze one-pot epoxide ring opening reaction in excellent yields in a very short reaction time. Various advantages associated with this protocol include simple workup procedure, short reaction times, and high product yields. High catalytic activity and ease of recovery, using an external magnetic field, are additional eco-friendly attributes of this catalytic system.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
