摘要: The combined use of 2D NMR correlation experiments and GIAO DFT 13C chemical shift calculations has allowed a reliable simple structural determination regioisomeric heterocyclic systems that originate from the reactions quinolinone or coumarin derivatives with hydroxylamine. In general, proposed method may find application in compounds. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
