A highly efficient electrophilic oxyselenation of propargylic amines with diselenides and CO2 under atmospheric pressure promoted by copper/DTBP is reported. Various biologically important selenyl 2-oxazolidinones were produced in moderate to excellent yields. The developed method features a broad substrate scope, easy scalability, and mild reaction conditions.
Solvent free one pot syntheses of highly substituted propargyl ethers and propargyl amines from propargyl alcohols catalyzed by recyclable alumina-sulfuric acid
develop an efficient protocol for the solvent-free synthesis of a wide variety of highlysubstituted propargyl ethers and amines using alumina-sulfuric acid as a recyclable heterogeneous solid acidcatalyst has been presented. This mild protocol tolerates a good number of acid-sensitive moieties and can be applicable to a diverse range of alcohols and amines accommodating a variety of substitution patterns
