Recent Advances in N-O Bond Cleavage of Oximes and Hydroxylamines to Construct N-Heterocycle

Molecules, 2023
Oximes and hydroxylamines are a very important class of skeletons that not only widely exist in natural products and drug molecules, but also a class of synthon, which have been widely used in industrial production.

From Mechanisms to Materials: Oximate Reactivity and Emerging Strategies for Organophosphate Detoxification. [PDF]

Chemphyschem
The development of effective strategies for the detoxification of organophosphorus (OP) nerve agents has evolved from the early mechanistic studies of François Terrier and collaborators, who first elucidated the exceptional nucleophilicity of α‐effect species such as oximes and hydroxamates, to the modern design of supramolecular and material‐based ...

Gold-Catalyzed Oxime–Oxime Rearrangement

Organic Letters, 2015
The gold-catalyzed reaction of pyrrole and indole oximes having a propargyl group attached to the nitrogen atom was studied. The selective 6-endo-dig mode of cyclization was observed for the terminal alkynes giving rise to the formation of pyrazine N-oxides in the presence of a gold catalyst.

Synthesis of Trifluoromethylated Monoterpene Amino Alcohols

Molecules, 2022
For the first time, monoterpene trifluoromethylated β-hydroxy-benzyl-O-oximes were synthesized in 81–95% yields by nucleophilic addition of the Ruppert–Prakash reagent (TMSCF3) to the corresponding β-keto-benzyl-O-oximes based on (+)-nopinone ...

A Comparison of the Therapeutic Efficacy of Conventional and Modern Oximes Against Supralethal Doses of Highly Toxic Organophosphates in Mice

Acta Medica, 1998
1. The therapeutic efficacy of various oximes (pralidoxime, obidoxime, methoxime, HI-6, HLö-7, BI-6) against supralethal nerve agent poisoning (soman, sarin, cyclosin) in mice was tested. 2. New oxime BI-6, synthesized in our laboratory, is significantly
