Catalytic asymmetric syntheses of isoxazoline-N-oxides under phase-transfer conditions
TL;DR: Catalytic asymmetric syntheses of various isoxazoline-N-oxides have been accomplished by asymmetric phase-transfer conjugate addition of bromomalonate to nitroolefins and subsequent ring-closing O-alkylation.

Molecular recognition of ketomalonates by asymmetric aldol reaction of aldehydes with secondary-amine organocatalysts
TL;DR: A diastereo- and enantioselective aldol reaction between aldehydes and a synthetically useful ketomalonate 1c as a hydrated form was developed and either anti- or syn-aldol adducts having a chiral tetrasubstituted carbon center were obtained in high enantiOSElectivities.

Catalytic Asymmetric Synthesis of Isoxazoline-N-oxides through Conjugate Addition–Cyclization under Phase-Transfer Conditions
TL;DR: In this paper, an asymmetric phase-transfer conjugate addition of bromomalonate to nitroolefin was proposed for the synthesis of isoxazoline-Noxides with tetrasubstituted carbon.

Catalytic Asymmetric Syntheses of Isoxazoline‐N‐oxides under Phase‐Transfer Conditions.
TL;DR: The conjugate addition/O-alkylation sequence under application of a chiral phase transfer catalyst proceeds with moderate to good enantioinduction as mentioned in this paper, which is the state-of-the-art performance.

Catalytic Asymmetric Synthesis of Isoxazoline-N-oxides Through Conjugate Addition—Cyclization under Phase-Transfer Conditions.
TL;DR: The application of a chiral phase-transfer catalyst gives the isoxazoline-Noxide products (III)/(V) with moderate to good yields and enantioselectivity as discussed by the authors.
