Studies toward funiculosin. Intramolecular carbonyl condensations using carboxamidimidazolide intermediates
摘要:
Internal enolate condensations, utilizing carboxamidimidazoles as activated wear, provide a general synthesis of the 3,5-disubstituted-4-hydroxy-2-pyridinone 2 as found in funiculosin. The novel all-syn-cyclitol, C-linked to the heterocyclic system, is prepared from croconic acid. Copyright (C) 1996 Elsevier Science Ltd
