A new class of calix[4]arene crown ethers with one or two bipyridines appended to the polyether ring (lariat calixcrowns) have been designed and synthesized; the luminescence properties of their Eu3+ and Tb3+ complexes have been studied in acetonitrile. In this solvent, long lifetimes for the metal emitting states and high metal-luminescence intensities obtained upon ligand excitation have been observed in both Eu3+ and Tb3+ complexes. The association constants in methanol have been determined for some of the complexes studied.

The stereoselective synthesis of 1- and 2-O-α-D-cellotriosyl-3-deoxy-2(R)- and 2(S)-glycerols, which determined the structure of rhynchosporoside produced by Rhynchosporium secalis, and their phytotoxicity toward the host plant (Hordeum vulgare) are described in detail.
Synthesis of Glyceryletherphosphatides. Preparation of 2-O-Acetyl-1-O--sn-glyceryl-3-phosphorylcholin ('Oleyl PAF'), of its Enantiomer and Some Analogous, Unsaturated Compounds

Syntheses of the unsaturated glyceroletherphospholipid 1a as an olefin-analog of 'Platelet Activating Factor' (PAF) are described together with the methods for the preparation of the enantiomer 1'a, the corresponding 'lyso compounds' 1b and 1'b and their positional isomers 21a, 21'a, 26, 26', 25, 25' obtained on formally exchanging the attachment site of the functional groups at the glycerol moiety.Structural assignments and optical purity of the compounds are confirmed.
