High stereoselectivity synthesis of Z-3-methyleneisoindolin-1-ones on a Cu/ETS-10 catalyst via domino coupling–cyclization without the use of protective groups and ligands

Abstract

Using Cu/ETS-10 to synthesize Z-3-methyleneisoindolin-1-ones through coupling–cyclization of 2-halobenzamides with aromatic alkynes in the absence of protected 2-halobenzamides and ligands.

“…The pyridine-adsorbed infrared spectrum was recorded on a Bruker TENSOR 27 spectrophotometer according to previous publication. 30,31 Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) of the samples were carried out on a SUPRA 5 field emission electron microscope and a JEM 2100F microscope.…”
