Popis: | The syntheses of iso-cladospolide-B, cladospolide-B and cladospolide-C are reported with 4S,5S,11S-configuration. Of the three stereogenic centres, the C-4/C-5 vic-diol was created by Evans aldol condensation, while the C-11 stereocentre was created by Jacobsen’s method. The synthesis of cladospolides 1–3 defined the absolute stereochemistry of these natural products. |
