Recently I am researching about ALKALOIDS; CHEMISTRY; 4-METHYLIDENEISOXAZOLIDIN-5-ONES, Saw an article supported by the National Science FoundationNational Science Foundation (NSF) [1407681]. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Brar, A; Unruh, DK; Ling, N; Krempner, C. The CAS is 500-22-1. Through research, I have a further understanding and discovery of 3-Pyridinecarboxaldehyde. Name: 3-Pyridinecarboxaldehyde
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.
