【摘要】本文测定了七种5,6-二取代-3,4-二氢化-2-吡喃酮和吡啶酮衍生物的¹³C NMR谱。对所有共振谱线进行了全面归属,并讨论了不同取代基和环内不同杂原子对化学位移值的影响。更多还原

【Abstract】 ¹³C NMR spectra of seven 5, 6-disubstituted-3, 4-dihydro-2-pyrone andpyridone derivatives were determinated in this paper. All of the resonance lines were fully assigned and the effects of substituents and heteroatoms in ring on chemical shifts were discussed.更多还原
