Ruthenium-catalyzed oxidative coupling/cyclization of isoquinolones with alkynes through C-H/N-H activation: Mechanism study and synthesis of dibenzo[a,g]quinolizin-8-one derivatives
The mechanism of [{RuCl2(p-cymene)}2]-catalyzed oxidative annulations of isoquinolones with alkynes was investigated in detail. The first step is an acetate-assisted C-H bond activation process to form cyclometalated compounds. Subse
Rh-catalyzed oxidative coupling between primary and secondary benzamides and alkynes: Synthesis of polycyclic amides
A methodology for the high yield and facile synthesis of isoquinolones from benzamides and alkynes via the oxidative ortho C-H activation of benzamides has been developed. Ag2CO3 proved to be an optimal oxidant when MeCN was used as
