The reduction of various conjugated homopropargylic alcohols with sodium bis(2-methoxyethoxy) aluminium hydride (Red-Al®) in ether or THF is described. The reaction takes place cleanly and rapidly, under mild conditions, to give (E)-homoallylic alcohols stereoselectively in good isolated yields.
介绍了在乙醚或四氢呋喃中用氢化双(2-甲氧基乙氧基)铝钠(Red-Al®)还原各种共轭均丙烯醇的方法。该反应在温和的条件下快速、干净地进行,以良好的分离产率立体选择性地得到 (E)-均丙烯丙基醇。
