The chemical sulfation of β-resorcylic acid esters was investigated by applying state of the art procedures for the synthesis and deprotection of 2,2,2-trichloroethyl protected sulfates as appropriate intermediates. The selectivity of monosulfation was studied and reaction optimization was performed considering the effect of the solvent, different bases as well as the sulfation reagent itself. Finally
β-间苯二酸酯的化学硫酸化通过应用2,2,2-三氯乙基保护的硫酸盐作为合适的中间体的合成和脱保护工艺进行了研究。研究了单硫酸化的选择性,并考虑了溶剂,不同的碱以及硫酸化试剂本身的影响进行了反应优化。最后,将获得的方案用于重要的共轭(掩蔽的)霉菌毒素玉米赤霉烯酮14-硫酸盐(铵盐)的首次合成,作为在生物分析和毒理学领域进一步研究的参考材料。
