In the study of parasitoids of the plane leaf miner Phyllonorycter platani during 2004, 18 polyphagous parasitoid species were recorded in four tree rows and four parks in Serbia (3 species of the family Ichneumonidae and 15 species of the family Eulophidae). Among the recorded parasitoids, the most significant were the species Minotetrastichus platanellus, Pediobius saulius and M. frontalis, f...

Disaccharides that contain 3-deoxy-d-manno-oct-2-ulosonic acid (Kdo) and d-glycero-d-talo-oct-2-ulosonic acid (Ko) substituted at the 8-position by 4-amino-4-deoxy-β-l-arabinopyranosyl (Ara4N) residues have been prepared. Coupling an N-phenyltrifluoroacetimidate-4-azido-4-deoxy-l-arabinosylglycosyl donor to acetyl-protected allyl glycosides of Kdo and Ko afforded anomeric mixtures of disacchari...
