Abstract
N-Substituted 4-methyl- and 4-ethylisoquinolone derivatives are prepared from different N-allylbenzamide derivatives in a single step through a ligand-free palladium-mediated intramolecular Heck cyclization.
Key words
isoquinolones - Heck cyclization - intramolecular cyclization - palladium acetate
