New fused lactones from indolizinediones via N-acyliminium ions
摘要:
N-Arylmethylphthalimidine-3-carboxylates 3 are good precursors for the synthesis of ketones 5a,b or enols 6c-e which upon acidic treatment led to lactones 7 via an N-acyliminium ion. (C) 1998 Elsevier Science Ltd. All rights reserved.
