AI Article Synopsis

  • The study presents a novel biogenetic synthesis strategy that combines electrooxidation and heterodimerization to generate various analogues of the fissoldhimine alkaloid.
  • Under acidic conditions, 2-alkoxypyrrolidine-1-carboxamides undergo Shono oxidation, resulting in the formation of -heterodimers with impressive yields and selectivity in their spatial arrangement.
  • The use of chiral phosphoric acid in enantioselective heterodimerization further enhances the process, yielding -heterodimers with high levels of enantioselectivity.

Article Abstract

This study develops a biogenetic synthesis strategy using electrooxidation and heterodimerization of -substituted pyrrolidine-1-carboxamides to create diverse analogues of the fissoldhimine alkaloid core. Under acidic conditions, 2-alkoxypyrrolidine-1-carboxamides from Shono oxidation formed -heterodimers with high yields and diastereoselectivity. Enantioselective heterodimerization using chiral phosphoric acid catalysis produced -heterodimers with high enantioselectivity.
