efficient method for converting methyl sulfones to sulfinic acids is described. The process involves alkylation with a benzylic halide, followed by in situ elimination of the resulting styrene in the presence of excess base to yield a sulfinic acid in a single reaction process. The usefulness of the alkylation–elimination sequence is demonstrated by generating a variety of sulfinic acids from methyl
描述了一种简单有效的将甲基砜转化为亚磺酸的方法。该方法包括用苄基卤化物进行烷基化,然后在过量碱的存在下在单个反应过程中原位消除所得的苯乙烯以产生亚磺酸。通过从甲基砜生成各种亚磺酸来证明烷基化消除序列的有用性。经由亚磺酸盐中间体获得了几种具有生物活性的甲基砜的后期功能化和14 C-标记。
