Manganese‐ Mediated Cascade Radical Oxidative Cyclization/1,6‐Conjugate Addition of Unsaturated Oximes with p‐Quinone methides: Facile Access to β,β‐Diarylmethine Isoxazolines

Chemistry - An Asian Journal, Год журнала: 2024, Номер unknown

Опубликована: Ноя. 9, 2024

A simple and efficient strategy for the synthesis of structurally diverse β,β-diarylmethine substituted isoxazoline derivatives have been developed. This approach employs a manganese-promoted oxidative cyclization coupled with 1,6-conjugate addition unsaturated oximes to p-quinone methides. The key features this study include formation C-O C-C bonds through intramolecular intermolecular interactions, facilitated by in situ generated iminoxyl radicals. isoxazolines, bearing wide range functional groups, were isolated high yields.
