Spiro cyclisations of N-acyliminium ions involving an aromatic π-nucleophile
摘要:
Spiro 2-pyrrolidin-5-ones were obtained from N-substituted succinimides by a two-step procedure, involving 5- or 6-endo-trig cyclisation of N-acyliminium ion intermediates with a tethered aromatic pi-nucleophile. (C) 2003 Elsevier Science Ltd. All rights reserved.
