Isoxazole derivativesR 0240 Stereoselective Intramolecular 1,3-Dipolar Nitrile Oxide Cycloaddition Reaction

of N-Formyl-β-nitroamides. — Starting from readily available nitroalkanes and form-amides, a new two-step stereoselective synthesis of bicyclic-4,5-dihydroisoxazoles is developed. The products are useful synthons in aza-heterocyclic chemistry. — (KADOWAKI, A.; NAGATA, Y.; UNO, H.; KAMIMURA*, A.; Tetrahedron Lett. 48 (2007) 10, 1823-1825; Dep. Appl. Mol. Biosci., Grad. Sch.
