protecting group for a phenol is conveniently unmasked under the conditions of the SNAr reaction with an activated aryl halide, producing diarylether products directly. The method is advantageous when the preparation of a phenol substrate requires O-protection, since the selection of the robust methanesulfonate as a latent phenol obviates a deprotection step prior to the SNAr reaction.
苯酚的甲磺酰基保护基在S N Ar反应条件下与活化的芳基卤化物方便地被掩盖,直接生产二芳基醚产物。该方法是有利的,当一个酚基片的制备需要ø -防护,由于鲁棒甲磺酸盐作为潜苯酚消除脱保护之前,在S步骤的选择Ñ的Ar反应。
