We have synthesized 7-fluoro-, 9-fluoro- and 11-fluoro- benzo[b]fluoranthene as part of a study designed to locate the molecular sites involved in the metabolic activation of the carcinogenic parent hydrocarbon. Analysis of the proton NMR spectra reveals the effect of fluorine substitution to be almost entirely localized in the substituted ring, the principal exception being a strong deshielding of
我们合成了7-氟-,9-氟-和11-氟-苯并[b]荧蒽,作为旨在定位与致癌母体烃代谢活化有关的分子位点的研究的一部分。质子NMR谱的分析表明,氟取代的作用几乎完全位于取代的环中,主要的例外是在空间拥挤的位点(即周向或伪湾区)中相对质子的强屏蔽作用。
