Two previously unknown lumazine derivatives, 1 and 2, have been isolated from the parasitic freshwater leech Limnatis nilotica. The structures of the compounds have been elucidated by NMR and unambiguously corroborated by chemical synthesis.

The use of platinum drugs in antitumour therapy is well established. An important drawback of these chemotherapeutics is the lack of selectivity for tumour cells, usually resulting in severe toxic side effects. A glucuronyl-platinum conjugate was des

In this paper, a glycosylation-based approach towards novel aminoglycoside analogues is presented. Three different cyclitol building blocks were condensed with different thioglycosides to give, after removal of the protective groups, several neamine-

Enantiomerically pure 4,6-diaminocyclohexenols are obtained from carbohydrate derived 1,7-dienes by ring-closing metathesis and palladium catalyzed allylic amination using o-nitrobenzenesulfonylamides as nucleophiles. In the latter reaction the use o
