Abstract

Several spiro 2-pyrrolidin-5-ones were obtained by a two-step procedure from N-substituted succinimides, involving spiro cyclisation of N-acyliminium ion intermediates in refluxing trifluoroacetic acid; in all cases cyclisation utilised a tethered aromatic p-nucleophile, and ring-closure followed 5- or 6-exo-trig pathways.
