Described here is the R3P/ICH2CH2I-promoted dehydroxylative sulfonylation of alcohols with a variety of sulfinates. In contrast to previous dehydroxylative sulfonylation methods, which are usually limited to active alcohols, such as benzyl, allyl, and propargyl alcohols, our protocol can be extended to both active and inactive alcohols (alkyl alcohols). Various sulfonyl groups can be incorporated,
此处描述的是 R 3 P/ICH 2 CH 2 I 促进的醇与各种亚磺酸盐的脱羟基磺酰化反应。与以前的脱羟基磺酰化方法通常仅限于活性醇(如苯甲基醇、烯丙基醇和炔丙醇)相比,我们的方案可以扩展到活性醇和非活性醇(烷基醇)。可以并入各种磺酰基,例如CF 3 SO 2和HCF 2 SO 2,它们是药物化学中感兴趣的氟化基团,其安装受到越来越多的关注。值得注意的是,所有试剂都很便宜且广泛可用,并且在 15 分钟的反应时间内获得了中等到高产率。
