  Stereochemically Reliable Syntheses of Pachastrissamine and Its 2-epi-Congener via Oxazolidinone Precursors from an Established Starting Material N-tert-Butoxycarbonyl-Protected Phytosphingosine

  摘要：

  Efficient, stereochemically unambiguous, total syntheses of pachastrissamine and its 2-epi-congener from the readily available common precursor (1R)-1-{(4S,5S)-2-oxo-4-[(trityl-oxy)methyl]-1,3-oxazolidin-5-yl}pentadecyl methanesulfonate are reported. Syntheses of (3aS,6R,6aR)- and (3aS,6S,6aR)-6-tetradecy-lhexahydro-2H-cyclopenta[d][1,3]oxazol-2-one by this route have unambiguously resolved a dispute over the structures of these products.

• Syntheses of sulfur and selenium analogues of pachastrissamine via double displacements of cyclic sulfate

  DOI：10.1039/c1ob05920c

  日期：——

  Bioisosteric analogues of pachastrissamine that contain sulfur and selenium atoms replacing the oxygen in the ring system, were efficiently prepared from a cyclic sulfate intermediate by sequential intermolecular and intramolecular SN2 displacement reactions of the dianions. The analogues exhibited cytotoxicities comparable to that of pachastrissamine.

  含有硫和硒原子的pachastrissamine生物等排素类化合物通过从一个环状硫酸盐中间体出发，经过二阴离子的顺序分子间和分子内SN2取代反应高效制备而成。这些类似物表现出与pachastrissamine相当的细胞毒性。
