An article BPh3-Catalyzed [2+3] Cycloaddition of Ph3PCCO with Aldonitrones: Access to 5-Isoxazolidinones with Exocyclic Phosphonium Ylide Moieties WOS:000481979100027 published article about ALKALOIDS; CHEMISTRY; 4-METHYLIDENEISOXAZOLIDIN-5-ONES in [Brar, Amandeep; Unruh, Daniel K.; Ling, Natalie; Krempner, Clemens] Texas Tech Univ, Dept Chem & Biochem, Box 41061, Lubbock, TX 79409 USA in 2019.0, Cited 43.0. Product Details of 500-22-1. The Name is 3-Pyridinecarboxaldehyde. Through research, I have a further understanding and discovery of 500-22-1
A method for the generation of 5-isoxazolidi-nones with exocyclic phosphonium ylide functionalities via [2+3] cycloaddition of Ph3PCCO and aldonitrones has been developed and applied in the synthesis of 4-alkylidene-5-isoxazolidinones via Wittig olefination. The reaction proceeds by BPh3 catalysis under mild conditions and with a broad substrate scope. A reaction pathway involving the activation of the aldonitrone via interactions with the Lewis acid BPh3 is proposed.
