Abstract
Pyrrolidine-2,5-dione was N-alkylated with five different 2-(3,4-dihydro-1-naphthelenyl)ethyl-4-methylphenylsulfonates to afford the corresponding imides, which on reduction with NaBH4 in MeOH at −10°C followed by intramolecular cyclisation in POCl3 afforded the corresponding title compounds.
