  Revisiting [3 + 3] Route to 1,3-Cyclohexanedione Frameworks:  Hidden Aspect of Thermodynamically Controlled Enolates

  摘要：

  We have revisited the traditional consecutive Michael-Claisen [3 + 3] process (MC-[3 + 3]) promising the synthesis of a cyclohexane-1,3-dione derivatives from nonactivated simple ketones and enoates and evaluated its potential in modern organic synthesis. Twenty to thirty examples were demonstrated to be effective. The reactions exhibited remarkable regioselectivity with the Michael addition proceeding through nucleophilic attack by the more hindered site of the ketones without exception. The subsequent Claisen condensation resulted in the formation of carbon-carbon bonds between less hindered site of the ketones and acyl carbon of the enoates. The MC-[3 + 3] process described is useful for the synthesis of Taxol A-ring synthons in multigram quantities and for the synthesis of other six-membered carbocyclic compounds. A number of control experiments have been conducted to provide strong support for the mechanism of this MC-[3 + 3].

  用的LiAlHα-完全取代的β酮膦酸酯的Dephosphonylation 4 ; 使用膦酸酯作为临时活化基团的酮的区域选择性烷基化

  摘要：

  β-酮膦酸酯的烷基化是通过用n -BuLi乳化β-酮膦酸酯，然后添加烷基卤来进行的。通过用LiAlH 4处理烯醇锂，然后用H 2 SO 4水溶液淬灭，将获得的α-完全取代的β-酮膦酸酯脱膦酰化。整个过程代表了酮区域选择性烷基化的新途径。

• Diphenylphosphinoyl-mediated synthesis of ketones
  作者：David J. Fox、Daniel Sejer Pedersen、Stuart Warren

  DOI：10.1039/b606873a

  日期：——

  α-Diphenylphosphinoyl ketones are selectively and sequentially alkylated at the α-position. Double lithiation and selective alkylation occurs at the less stabilised γ-position. Dephosphinoylation of the alkylation products gives ketones. Mono-alkylation is selective, highly crystalline intermediates are formed and a one-pot strategy is possible. The method is ideally suited for the preparation of acid-sensitive ketones.

  α-二苯基膦酰基酮在α位上选择性且顺序性地进行烷基化。双锂化和选择性烷基化发生在较不稳定的γ位。脱膦酰化得到的烷基化产物是酮。单烷基化具有选择性，形成的中间体晶体高度结晶，且可以进行一步完成的方法。该方法非常适合制备酸敏感的酮。
