development of a useful procedure for the removal of thioacetals and thioketals using Dess-Martin periodinane (DMP) reagent. In contrast to existing methods, this protocol offers general reactivity, compatibility with a wide range of functional groups, and convenient reaction times. Also discussed are chemoselectivity experiments involving functionalities that may be subject to oxidation by DMP, qualitative
[反应:见正文]本文介绍了使用Dess-Martin高碘烷(DMP)试剂去除硫缩醛和硫缩酮的有用方法的开发。与现有方法相比,该协议具有一般的反应性,与各种官能团的相容性以及方便的反应时间。还讨论了化学选择性实验,涉及的功能可能会被DMP氧化,底物对水解速率的定性影响以及硫代乙缩醛向乙缩醛的直接转化。
