The molecular structures of the three main haemolytic compounds (Fj1, Fj2 and Fj3) isolated from the ichthyotoxic microalgal species Fibrocapsa japonica have been investigated by NMR, LC-ESI-MS, ESI-MS-MS, IR, GC-MS and GC-HRMS methods. They are polyunsaturated fatty acids which we identified as: 6,9,12,15-octadecatetraenoic acid (OTA, C18:4ω3), 5,8,11,14,17-eicosapentaenoic acid (EPA, C20:5ω3) and...
The synthesis of phthalocyanines 1a and 1b appended with four glycoluril modules is presented. 1 H NMR spectroscopy showed that 1a and 1b self-assemble by means of hydrogen bonding to form discrete dimers. Capsule formation is solvent dependent where the dimeric assembly is most pronounced in aromatic solvents.
Two new chiral glyco-oxazolidin-2-one auxiliaries based on d-glucose are described. Some N-acyl derivatives were synthesized and used in dialkylboron-mediated asymmetric aldol reactions. All reactions delivered as the major diastereomer those predicted by the Zimmerman-Traxler model and were separated by column chromatography and mostly isolated in moderate to good yields.
