Total Synthesis of (±)-Paroxetine by Diastereoconvergent Cobalt-Catalysed Arylation.

Despiau CF, Dominey AP, Harrowven DC, Linclau B - European J Org Chem (2014)

Bottom Line: A total synthesis of paroxetine is reported, with a diastereoselective and diastereoconvergent cobalt-catalysed sp(3)-sp(2) coupling reaction involving a 3-substituted 4-bromo-N-Boc-piperidine (Boc = tert-butoxycarbonyl) substrate as a key step.A 9:1 diastereoselectivity was obtained, while a control experiment involving a conformationally locked 3-substituted 4-bromo-tert-butyl cyclohexane ring proceeded with essentially complete stereoselectivity.
