  Towards EPC-syntheses of the structural class of cochleamycins and macquarimicins. Part 1: EPC-synthesis of the hydrindene subunit of the cochleamycins

  摘要：

  A racemic as well as an EPC-synthesis of the cis-hydrindene subunit of the cochleamycins, physiologically active microbial secondary metabolites, are reported. The five stereogenic centres of this subunit are introduced in high stereoselectivity in a short sequence by intermolecular Diels-Alder reaction, stereoselective methylation and hydride reduction. Cyclisation via nucleophilic addition, acidic fragmentation, regioselective Shapiro reaction and inversion of a secondary alcohol are the further key steps of these syntheses. (c) 2007 Elsevier Ltd.

  Towards EPC-syntheses of the structural class of cochleamycins and macquarimicins. Part 2: EPC-synthesis of the hydrindene subunit of the macquarimicins

  摘要：

  The EPC-synthesis of the cis- hydrindene subunit of the macquarimicins, antibiotics with antitumour and anti-inflammatory activity, has been achieved. Desymmetrization of cis-1,4-cyclopent-2-enediol was succeeded by Diels-Alder reaction and functional group transformations to a tricyclic ketone. Regio- and stereoselective methylation via Claisen condensation and hydrogenation was followed by nucleophilic, intramolecular addition, reduction and acidic fragmentation. Further functional group transformations led to the target molecule. (c) 2007 Elsevier Ltd. All rights reserved.
