Abstract

Abstract A mixed homogeneous-heterogeneous catalysis that exploits a multi-task palladium catalyst has been developed for one-pot sequential Heck-reduction-cyclization (HRC) reactions leading to novel 4-benzyl-1, 2-dihydroisoquinolin-3-ones. The HRC sequence requires mild conditions and allows the separation of the palladium residues under the form of an in situ generated Pd (0)/C catalyst by simple filtration. The homemade and recovered ...
