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 ...

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 ...

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 ...

Synthesis of isoxazoline analogs of stellettins

Organic & Biomolecular Chemistry
(±)-Stellettin analogs featuring an isoxazoline ring were synthesized. Pharmacological evaluation of the analogs revealed that the α,β-unsaturated ketone structures in stellettins might be important to their cytotoxic activity.
