base-promoted, allene-mediated cyclization of the alkyne moiety onto the nearby aromatic ring, substantial amount of the ketone resulting from hydration of the alkyne with adventitious water was discovered. The formation of the ketone of the anti-Markovnikov alkyne hydration was developed into a preparative method. This method, alternative to the common acid-and metal-catalyzed approaches, may be of particular
在尝试将 5-甲基-2-苯基-1-(3-苯基-丙-2-yn-1-基)-1 H-咪唑参与碱促进、丙二烯介导的炔部分环化到在芳环附近,发现了大量由炔与外来水水合产生的酮。发展了抗马氏炔水合形成酮的制备方法。当需要在酸不稳定基团存在下进行炔水合时,该方法可以替代常见的酸和金属催化方法,可能特别有用。
