Methyl propargyl ethers, obtained from carbonyl compounds by successive treatment with an acetylide and MeI, were easily converted to the corresponding α,β-unsaturated ketone by regioselective hydration of acetylenic moiety followed by elimination of methanol under the catalytic action of Au(III).
通过用乙炔和 MeI 连续处理从羰基化合物中获得的甲基炔丙基醚,通过炔部分的区域选择性水合,然后在 Au(III) 的催化作用下消除甲醇,很容易转化为相应的 α,β-不饱和酮。
