Abstract
AbstractAcylation of nitroalkylmalonates was found to yield substituted isoxazoline derivatives. This redox‐neutral transformation has a wide substrate scope and produces target products with yields up to 92%. Various substituents (aryl, alkyl, and ester) at the C3 and C4 positions of the resulting isoxazolines were also tolerated. A quick assembly of the isoxazoline ring starting from nitroalkenes and malonates was successfully developed. Control experiments showed that the intramolecular ring closure is the most likely key mechanistic step. Subsequent transformations into pyrrolidine and furane derivatives demonstrated the synthetic utility of the obtained products.magnified image
