  d-Glucosamine-Derived Synthons for Assembly of l-threo-Sphingoid Bases. Total Synthesis of Rhizochalinin C

  摘要：

  A five-step transformation of D-glucosamine, commencing with indium-mediated Barbier reaction without isolation of intermediates, into (R,R)-2-aminohex-5-ene-1,3-diol in 45-51% is described. The latter is a useful synthon for assembly of L-threo-sphingoid bases: long-chain aminoalkanols and aminoalkanediols with configurations antipodal to that found in mammalian D-erythro-sphingosine but prevalent among invertebrate-derived sphingolipids. The utility of the method is demonstrated by the first total synthesis of rhizochalinin C, the long-chain, "two-headed" sphingoid base aglycon of the natural product rhizochalin C from the marine sponge Rhizochalina incrustata.

  Rhizochalins C and D from the Sponge Rhizochalina incrustata. A Rare threo-Sphingolipid and a Facile Method for Determination of the Carbonyl Position in α,ω-Bifunctionalized Ketosphingolipids

  摘要：

  Rhizochalins C and D (1, 2), new representatives of two-headed glycosphingolipids, were isolated from the sponge Rhizochalina incrustata. Rhizochalin D is an unexpected C-29 homologue of the canonical C-28 dimeric sphingolipid structures. Their structures including absolute configurations were established using spectroscopic data, micromolar-scale Baeyer-Villiger oxidation, and LCMS interpretation of the products. Application of the latter method leads to a revision of the structure of oceanapiside and placement of the keto group at C-18 rather than C-11.
