Phosphane-Free Pd0-Catalyzed Cycloamination and Carbonylation with Pd(OAc)2 and Cu(OAc)2 in the Presence of K2CO3: Preparation of Benzocyclic Amines and Benzolactams
quinolines in a catalytic system based on Pd(OAc)2 and Cu(OAc)2 in the presence of K2CO3. Application of the method to substrates containing isoquinolinerings – the 1-(o-bromobenzyl)-3,4-dihydroisoquinolines 6, the 1-(o-bromobenzyl)-1,2,3,4-tetrahydroisoquinolines 7, and the 1-(o-bromophenethyl)isoquinolines 9 – provided the indolo[2,1-a]isoquinoline and dibenzo[a,f]quinolizine ringsystems 8 and 10.
