  Direct Conversion of β-Hydroxyketones to Cyclic Disiloxanes

  摘要：

  beta-Hydroxyketones can be directly converted to cyclic disiloxanes using diphenylchlorosilane in the presence of imidazole and an amine base. The reaction is proposed to proceed via a nucleophilic activation mechanism through a cyclic chairlike transition state affording hydrosilylated products with high diastereoselectivity.

  Hg(OTf)2-Catalyzed Instantaneous Hydration of β- and δ-Hydroxy Internal Alkynes with Complete Regioselectivity

  摘要：

  在温和条件下，通过Hg(OTf)2催化的β-和δ-羟基内炔的水合反应可以瞬间完成，并且具有完全的区域选择性，生成酮类化合物，而没有羟基的内炔的水合反应则非常缓慢，且生成酮的混合物。如果羟基距离三键超过五个碳原子，那么它对水合反应几乎没有显著影响。

  air: A convenient and general iron-catalyzed oxidation of internal olefins, electron-deficient olefins, and styrenes to ketones by using 1 atm of air as the sole oxidant has been developed. This protocol efficiently incorporates atmospheric O2 into synthetically useful compounds under mild reaction conditions, which renders it environmentally benign, economical, and operationally simple.

  New acyl anion equivalents bearing a hydroxyl group at the β-position have been developed. Treatment of 3-benzyloxy-1-isocyanopropenes with lithium diisopropylamide (LDA) in THF at −78 °C generated the 1-lithio compounds, which reacted with alkyl halides to afford the corresponding 1-alkylated products in good yields. Acid hydrolysis of these alkylated products followed by hydrogenolysis of the resulting

  已经开发出在β位带有羟基的新的酰基阴离子当量。在-78°C下用二异丙基氨基锂在THF中处理3-苄氧基-1-异氰基丙烯，生成1-硫代化合物，该化合物与卤代烷反应，以高收率得到相应的1-烷基化产物。这些烷基化产物进行酸水解，然后将所得的β-苄氧基乙基酮进行氢解，生成β-羟乙基酮。
