  A Diastereoselective Oxa-Pictet–Spengler-Based Strategy for (+)-Frenolicin B and epi-(+)-Frenolicin B Synthesis

  摘要：

  An efficient diastereoselective oxa-Pictet - Spengler reaction strategy was developed to construct benzoisochroman diastereomers. The utility of the reaction was demonstrated in the context of both the total synthesis of naturally occurring pyranonaphthoquinones (+)-frenolicin B and epi-(+)-frenolicin B as well as a range of frenolicin precursor analogs. The method is versatile and offers exquisite stereocontrol and, as such, offers a synthetic advance for the synthesis of pyranonaphthoquinone analogs.

  Provided herein are pyranonaphthoquinone compounds and methods of using pyranonaphthoquinone compounds. The method of using the pyranonaphthoquinone compounds includes selectively inhibiting 4E-BP1 phosphorylation by administering at least one pyranonaphthoquinone or pyranonaphthoquinone analog to a subject in need thereof. The pyranonaphthoquinone compounds includes a structure according to Formula I:

• Efficient Synthesis of (+)-Kalafungin and (-)-Nanaomycin D by Asymmetric Dihydroxylation, Oxa-Pictet-Spengler Cyclization, and H₂SO₄-Mediated Isomerization
  作者：Reinhard Brückner、Rodney Fernandes

  The pyranonaphthoquinone antibiotics and antitumor agents (+)-kalafungin (1) and (-)-nanaomycin D (3 = ent-1) were synthesized from 1,5-napthalenediol (13) in 11 steps. Stereocontrol was high: 99.5 ee/93% diastereoselectivity for 1, 98.5% ee/94% ­diastereoselectivity for 3. Enantiocontrol was achieved by the asymmetric dihydroxylation of the β,γ-unsaturated ester 9. Dia­stereocontrol was realized in the final step by an almost complete epimerization in H2SO4.

  通过 11 个步骤从 1,5-萘二醇（13）合成了吡喃萘醌类抗生素和抗肿瘤药物 (+)-kalafungin (1) 和 (-)-nanaomycin D (3 = ent-1)。这两种化合物的立体选择性很高：1 的非对映选择性为 99.5%，3 的非对映选择性为 98.5%。δ,δ-不饱和酯 9 的不对称二羟基化实现了对映体控制。在最后一步，通过在 H2SO4 中几乎完全的外延化反应实现了非对映控制。

  日期：2008.6

  A highly enantioselective synthesis of (−)- and (+)-juglomycin A, a quinone antibiotic is described. The synthesis is completed in eight steps, and 19% overall yield and in a high enantioselectivity of 99.5% [for (−)-juglomycin A] and 98.5% [for (+)-juglomycin A]. The synthetic strategy features an efficient combination of the Dötz annulation reaction and asymmetric dihydroxylation as the keys steps

  Syntheses of the diastereoisomeric 5-hydroxy-2-(4′-hydroxy-γ-butyrolacton-5′-yl)-1,4-naphthoquinones (1) and (2) and their 5-deoxy-analogues (3) and (4) are described. The stereochemistries of the latter, being defined through unambiguous synthesis, permit the assignment of the configurations of (1) and (2)(which were obtained from a single precursor) and also those of the natural products, juglomycins
