Strong deshielding in aromatic isoxazolines

Magnetic Resonance in Chemistry, 2015
AbstractVery strong proton deshielding was found in di/tri‐aromatic isoxazoline regioisomers prepared from acridin‐4‐yl dipolarophiles and stable benzonitrile oxides (BNO). Three alkenes, (acridin‐4‐yl)‐CHCH‐R (R = COOCH3, Ph, and CONH2), reacted with three BNO dipoles (2,4,6‐trimethoxy, 2,4,6‐trimethyl, 2,6‐dichloro) to give pairs of target ...

Electrocatalytic Isoxazoline–Nanocarbon Metal Complexes

Journal of the American Chemical Society, 2021
We report the synthesis of new carbon-nanomaterial-based metal chelates that enable effective electronic coupling to electrocatalytic transition metals. In particular, multiwalled carbon nanotubes (MWCNTs) and few-layered graphene (FLG) were covalently functionalized by a microwave-assisted cycloaddition with nitrile oxides to form metal-binding ...

Visible-Light-Mediated Three-Component Strategy for the Synthesis of Isoxazolines and Isoxazoles.

Organic Letters
Isoxazolines and isoxazoles commonly serve as core structures of many therapeutic agents and natural products. However, the metal-free and catalysis-free strategy for the synthesis of these privileged motifs at room temperature remains a challenging task.

Synthesis of 3-Acyl-isoxazoles and Δ2-Isoxazolines from Methyl Ketones, Alkynes or Alkenes, and tert-Butyl Nitrite via a Csp3-H Radical Functionalization/Cycloaddition Cascade.

Organic Letters, 2019
A novel metal-free tandem Csp3-H bond functionalization of ketones and 1,3-dipolar cycloaddition has been developed. An efficient approach to a variety of oxazole and isoxazoline derivatives is demonstrated using the 1,3-dipolar cycloaddition of alkynes ...
