Achiral organoiodine-functionalized helical polyisocyanides for multiple asymmetric dearomative oxidations.

Abstract in brief

• The study discusses the development of achiral organoiodine-functionalized helical polyisocyanides, which serve as catalysts for multiple asymmetric dearomative oxidation reactions, achieving high yields and enantiomeric excesses up to 95%.
• The helicity of the polymer backbone (left- or right-handed) can be reversed to switch the enantioselectivity of the catalyst, demonstrating control over the reaction outcome.
• These polymer catalysts can be easily recovered and reused in various oxidation reactions without losing their effectiveness or selectivity, making them practical for repeated use.]
