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.

Divergent synthesis of polysubstituted isoxazoles, isoxazoline N-oxides, and dihydroisoxazoles by a one-pot cascade reaction

open access: yesTetrahedron, 2017
An efficient one-pot synthesis of a new class of 3,4,5-trisubstituted isoxazoline N-oxides/isoxazoles and dihydroisoxazoles is developed by a green approach from aromatic and aliphatic aldehydes by controlling the reaction conditions.
