Cycloaddition reactions of nitrosoalkenes, azoalkenes and nitrile oxides mediated by hydrotalcite [PDF]

open access: yes, 2012
Mg:Al 3:1 hydrotalcite (Ht), used in catalytic quantities, promotes the generation of nitrosoalkenes, azoalkenes and nitrile oxides. These can be intercepted in situ by heterocycles and olefins in [4+2] and [3+2] cycloaddition reactions, producing ...

tert-Butyl Nitrite-Mediated Domino Synthesis of Isoxazolines and Isoxazoles from Terminal Aryl Alkenes and Alkynes.

open access: yesJournal of Organic Chemistry, 2017
A sequential construction of C-C, C-O, C═N, and C═O bonds from alkenes leading to the direct synthesis of isoxazolines in the presence of tert-butyl nitrite, quinoline, and the Sc(OTf)3 catalyst in DCE at 80 °C has been accomplished.

Interactions between prosulfocarb and trifluralin metabolism in annual ryegrass (Lolium rigidum)

open access: yesPest Management Science, Volume 81, Issue 2, Page 618-630, February 2025.
In Lolium rigidum, there is a relationship between trifluralin metabolism and prosulfocarb activation, but not between metabolism of pyroxasulfone and prosulfocarb. Abstract BACKGROUND Cross‐resistance between pre‐emergence herbicides is developing in Australian populations of annual ryegrass (Lolium rigidum Gaud.).

Hair fragility (trichorrhexis nodosa) in alopecic Pomeranian dogs

open access: yesVeterinary Dermatology, Volume 36, Issue 1, Page 64-73, February 2025.
Background – Alopecia associated with hair cycle arrest (HCA, Alopecia X) is well‐recognised in Pomeranian dogs. The authors are unaware of reports of hair fragility in affected dogs. Hypothesis/Objectives – Following the observation of frequent hair shaft abnormalities in alopecic Pomeranians, we hypothesised that hair fragility events would be more ...
