Isoxazolin-5-one

Journal of the Chemical Society C: Organic, 1971
The reaction paths leading from ethyl propiolate to isoxazolin-5-one (II) and isoxazolin-3-one (III) are discussed and shown to be pH-dependent. The chemical and tautomeric properties of compound (II) are consistent with the known behaviour of its derivatives.

Isoxazoline

2005
The first part of the presented work deals with the enantioselective synthesis of isoxazolines. The synthetic approach involves the asymmetrically catalysed 1,3-dipolar cycloaddition of nitrones to acetylenes. Therefore electrondeficient mono- and bifunctionalysed as well as electronrich triplebond systems, in combination with electronrich and ...

Insecticidal quinoline and isoquinoline isoxazolines

Bioorganic & Medicinal Chemistry Letters, 2014
A series of quinoline and isoquinoline isoxazolines have been designed as pesticides for crop protection. Herein we reported the chemical synthesis, biological activity and structure-activity relationships. The isoquinoline derivative, such as 3i, is discovered as potent new class of isoxazoline insecticide which is competitive with commercial ...

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 ...

Photochemistry of condensed isoxazolines

Monatshefte für Chemie Chemical Monthly, 1994
The condensed bridged isoxazolines4 are rearranged on irradiation with a low-pressure mercury lamp exclusively into condensed derivatives of tetrahydropyridine5. The selectivity of the rearrangement is due to a stabilization of the biradical8 by the overlap of the radical-electrons with π-electrons of the C=C double bond and the heterocyclic ring ...
