  Diastereoselective Synthesis of Protected syn 1,3-Diols:  Preparation of the C16−C24 Portion of Dolabelides

  摘要：

  We have designed a new method to make synthons encompassing a protected syn 1,3-diol motif and an aldehyde a to the 1,3-dioxane ring. An additional stereocenter was also created, potentially leading to stereochemically defined 1,2,4-triols. This method was successfully applied to the synthesis of the C16-C24 portion of Dolabelides.

A diazo group was introduced as a protecting group for an enolizable ketone. We were unable to bring about the envisioned biomimetic aldol addition cascade and gained insights into the feasibility of this process by DFT calculations. As an alternative approach to enterocin

• Studies on C18-C20 Aldol Couplings of Rhizopodin

  日期：——

  The aldol addition of an enol(ate) to a carbonyl compound is one of the most powerful and versatile C-C bond forming reactions. In complex target synthesis the coupling of two chiral partners may complicate the stereochemical outcome by multiple stereoinductions. Here, we report studies on pivotal aldol couplings employed in the rhizopodin synthesis, detailing the various directing effects exerted by the stereogenic centers present in this sterically hindered connection.

• Stereoselective Synthesis of 1,3-<i>anti</i> Diols by an Ipc-Mediated Domino Aldol-Coupling/Reduction Sequence
  作者：Michael Dieckmann、Dirk Menche

  DOI：10.1021/ol3033303

  日期：2013.1.4

  A novel domino process for 1,3-anti diol synthesis by the union of a methyl ketone with an aldehyde is described. The operationally simple procedure is based on an Ipc-boron-aldol coupling and subsequent Ipc-mediated reduction of the intermediate beta-hydroxy-ketone. The sequence proceeds with excellent anti-selectivities and enables the rapid construction of complex polyketide fragments.
