Total synthesis of (±)-paroxetine by diastereoconvergent cobalt-catalysed arylation

, 2014
A total synthesis of paroxetine is reported, with a diastereoselective and diastereoconvergent cobalt-catalysed sp3–sp2 coupling reaction involving a 3-substituted 4-bromo-N-Boc-piperidine (Boc = tert-butoxycarbonyl) substrate as a key step.
