A convenient set of bidentate pyridine ligands for combinatorial synthesis
摘要:
Synthesis is reported of five pyridine-containing bidentate ligands bearing nucleophilic groups at different positions. Their efficient solid-phase alkylation was demonstrated in the synthesis of a small library. These ligands are attractive building blocks for the construction of libraries of metal-binding compounds for various purposes. (C) 1999 Elsevier Science Ltd. All rights reserved.

This study focusses on a new concept for oligosaccharide synthesis based on 4-(pyridin-2-yl)thiazol-2-yl thioglycosides that can either act as effective glycosyl donors or can be deactivated by stable bidentate complexation with palladium(II) bromide.

The syntheses of BEDT-TTF (ET) derivatives with potential metal ion binding pyridyl, bipyridyl and terpyridyl groups is achieved either by stepwise construction of the organosulfur core or via reactions of hydroxymethyl-ET for which a cheap and efficient four step route is reported. The tosylate of hydroxymethyl-ET, reported for the first time, undergoes nucleophilic substitutions with pyridyl, bipyridyl-
