This invention relates to isoindole derivates of Formula I
to pharmaceutical compositions comprising such derivatives, and to methods of treatment comprising administering of such derivatives.
A radical cascade involving a 5-exo-dig cyclization followed by a 6-endo-trig radical trapping transforms ynamides into heterogeneous polycyclic compounds in good yields. This leads interestingly to the formation of isoindols, isoindolinones, and pyridoisoindolones. [reaction: see text]
Synthesis of 3,4-Dihydro-2H-pyrido[1,2-b]isoindol-1-one and 3,4-Dihydro-2H-pyrido[1,2-b]pyrrolidin-1-one Functionalized at the C-6 Position by an Intramolecular Horner-Wadsworth-Emmons Reaction
Novel polyheterocycles were prepared from a new annellation reaction which proceeds by nucleophilic substitution followed by an intramolecular Horner-Wads-worth-Emmons reaction between imides and beta-functionalized phosphonates.
