The Dess-Martin Periodinane (DMP) [1,1,1-triacetoxy-1,1-dihydro-1,2-benziodoxol-3(1H)-one], oxidatively deoximates aldoximes as well as ketoximes in very high yields, smoothly in short time, and under mild conditions. Deoximation occurs selectively in the presence of primary, secondary, and benzylic alcohols, O-methyl oximes, tosylhydrazones, and acid sensitive groups/moieties.
Dess-Martin高碘烷(DMP,即[1,1,1-三乙酰氧基-1,1-二氢-1,2-苯并碘氧杂环戊烯-3(1H)-酮])能高效且快速地在温和条件下氧化脱氧肟化醛肟及酮肟,产率极高。在含有伯醇、仲醇、苄醇、O-甲基肟、对甲苯磺酰腙以及对酸敏感基团的条件下,脱氧肟化反应能够选择性地进行。
