Asymmetric Synthesis of Functionalized 2-Isoxazolines. [PDF]

open access: yesACS Omega
The asymmetric synthesis of the isoxazoline skeleton was achieved by the oxidation of hydroxylaminoalkyl furan prepared from simple starting materials: 2-methylfuran and (S)-epichlorohydrin. The synthesis features an NBS-mediated oxidation of hydroxylaminoalkyl furan to give an α,β-unsaturated ketone intermediate which cyclized to the isoxazoline.
