  Spiroaminal model systems of the marineosins with final step pyrrole incorporation

  摘要：

  In this Letter, we describe a short, six step enantioselective route to spiroaminal lactam model systems reminiscent of marineosins A and B that has been developed starting from either (R)- or (S)-hydroxysuccinic acid, respectively, in similar to 9% overall yield. This route enables late stage incorporation of the pyrrole ring at C5 via nucleophilic displacement of an iminium triflate salt. (C) 2013 Elsevier Ltd. All rights reserved.

  A direct approach to the synthesis of indolizidine and quinolizidine scaffolds of iminosugars is described. The presented strategy is based on a one-pot sugar lactam reduction with Schwartz’s reagent followed by a diastereoselective Mannich/Michael tandem reaction of the resulting sugar imine with Danishefsky’s diene. The stereochemical course of the investigated reaction has been explained in detail

  Cephalimysin A is a potent anticancer natural product and its structure remains to be fully elucidated. To solve the stereochemical issue, a stereoselective synthesis of its spirofuranone-γ-lactam core was performed in a cascade fashion. The absolute configuration of key spiro stereogenic center was introduced based on d-malic acid derived imide and confirmed by a stereospecific derivatization.

  Analytical HPLC methods for the determination of the enantiomeric excess of N-protected malimides 1 as well as the corresponding pyrrolidinol 5 and tartarimides 2 and 3 have been established. On this basis, a study to reveal the racemization step in the synthesis of pyrrolidinols from alpha-hydroxyacids, via chiral cyclic alpha-hydroxyimides, has been undertaken. It was confirmed that the known, one-step method for the synthesis of the N-protected chiral cyclic imides from alpha-hydroxydiacids proceeded with little racemization, and partial racemization has been proven to occur during the reduction of the resultant imide la with LAH to yield the corresponding pyrrolidinol 5. Conditions have been defined in order to avoid racemization in the LAH reduction step. (C) 2011 Elsevier Ltd. All rights reserved.
