Imidazole-1-sulfonate, a new type of leaving group by remote activation, allows facile SN2 substitution reactions at sterically crowded centers with various nucleophiles under mild conditions. It could be easily prepared from alcohols with cheap reagents in quantitative yield.
咪唑-1-磺酸盐是一种通过远程激活的新型离去基团,可在温和条件下在空间拥挤的中心与各种亲核试剂进行简便的S N 2取代反应。它可以很容易地由具有廉价试剂的醇以定量产率制备。
