Rearrangement of cis and trans-2-methyl-1-(substituted phenyl)isoindolinium 2-methylides
摘要:
Fluoride ion induced desilylation of cis-2-methyl-1-(substituted phenyl)-2-[(trimethylsilyl)methyl] isoindolinium iodides cis-5 gave mixtures of the Sommelet-Hauser rearrangement products 7 and the Stevens products 8 in a ratio about 8.5:1.5. Similar treatments of the trans-isomers (trans-5) afforded exclusively 8. The pathways of the ylide rearrangement are discussed.

The present invention relates to compounds for their use in the reactivation of butyrylcholinesterase. Such compounds are useful in the treatment or prevention of the intoxication with at least one organophosphorus nerve agent. The invention also relates to pharmaceutical compositions and kits comprising said compounds, and compounds per se.
