  An enantiomerically pure epoxyorganolithium reagent for the synthesis of oligo(tetrahydrofurans) by an epoxide-cascade reaction

  摘要：

  Enantiomerically pure oligo(tetrahydrofurans) 17 and 18 have been prepared using an epoxide cascade reaction. The polyepoxide precursors 13 and 14 were synthesized using the enantiomerically pure epoxyorganolithium reagent 3. Thus, addition of 3 to the THF aldehyde 11 gave alcohol 12 with a high Cram selectivity of 95:5.

  New Antibacterial Agents Derived from the DNA Gyrase Inhibitor Cyclothialidine

  摘要：

  Cyclothialidine (1, Ro 09-1437) is a potent DNA gyrase inhibitor that was isolated from Streptomyces filipinensis NR0484 and is a member of a new family of natural products. It acts by competitively inhibiting the ATPase activity exerted by the B subunit of DNA gyrase but barely exhibits any growth inhibitory activity against intact bacterial cells, presumably due to insufficient permeation of the cytoplasmic membrane. To explore the antibacterial potential of 1, we developed a flexible synthetic route allowing for the systematic modification of its structure. From a first set of analogues, structure-activity relationships (SAR) were established for different substitution patterns, and the 14-hydroxylated, bicyclic core (X) of 1 seemed to be the structural prerequisite for DNA gyrase inhibitory activity. The variation of the lactone ring size, however, revealed that activity can be found among 11- to 16-membered lactones, and even seco-analogues were shown to maintain some enzyme inhibitory properties, thereby reducing the minimal structural requirements to a rather simple, hydroxylated benzyl sulfide (XI). On the basis of these "minimal structures" a modification program afforded a number of inhibitors that showed in vitro activity against Gram-positive bacteria. The best activities were displayed by 14-membered lactones, and representatives of this subclass exhibit excellent and broad in vitro antibacterial activity against Gram-positive pathogens, including Staphylococcus aureus, Streptococcus pyogenes, and Enterococcus faecalis, and overcome resistance against clinically used drugs. By improving the pharmacokinetic properties of the most active compounds (94, 97), in particular by lowering their lipophilic properties, we were able to identify congeners of cyclothialidine (1) that showed efficacy in vivo.

  A new approach to the synthesis of the C7-26 fragment of amphidinolides G and H was developed. In the sequence, the C7-18 portion of this fragment was synthesized using an acetylide coupling protocol, while an Evans alkylation and Sharpless asymmetric dihydroxylation were employed as key steps in construction of the C19-26 subfragment. Finally, both of these units were joined by utilizing an aldol
