Stereoselective Dehydroxyboration of Allylic Alcohols to Access (<i>E</i>)-Allylboronates by a Combination of C–OH Cleavage and Boron Transfer under Iron Catalysis
Iron-catalyzed direct SN2′ dehydroxyboration of allylic alcohols has been developed to access (E)-stereoselective allylboronates. Allylic alcohols with diverse structures and functional groups, especially derived from natural products, underwent smooth transformation. The six-membered ring transition state formed by allylic alcohols and iron–boron intermediate was indicated to be the key component
铁催化的烯丙醇直接 S N 2' 脱羟基硼酸已被开发用于获得 ( E )-立体选择性烯丙基硼酸酯。具有多种结构和官能团的烯丙醇,特别是来自天然产物的烯丙醇,经历了平稳的转变。由烯丙醇和铁-硼中间体形成的六元环过渡态被证明是参与硼基团转移、C-OH键活化和立体选择性控制的关键成分。
Selective Aerobic Oxidation of Allylic Alcohols to Carbonyl Compounds Using Catalytic Pd(OAc)<sub>2</sub>: High Intramolecular Selectivity
Allylicalcohols were selectively oxidized into aldehydes or ketones using a Pd(OAc) 2 -Et 3 N-O 2 system. Diols with one -allylic function were selectively oxidized, with one of the hydroxyl groups remaining untouched.
使用 Pd(OAc) 2 -Et 3 NO 2 系统将烯丙醇选择性氧化成醛或酮。具有单烯丙基官能团的二醇被选择性氧化,其中一个羟基保持不变。
