A variety of differently substituted and diversely N-(sulfanyl)hydroxyalkyl functionalized isoindolinones and isoquinolones have been obtained by anionic cyclization of cyclic bromobenzyl or bromophenethylcarbamates and thiocarbamates.
A variety of poly and diversely substituted isoindolinones fused with six-membered heterocyclic moieties has been readily assembled through a sequence involving metalation of N-chloroalkylated models, subsequent interception with appropriate electrophiles and ultimate intramolecular annulation reaction.
