monosaccharides (D-galactose, D-glucose and D-xylose) per-O-acetylated glycosyl isothiocyanates and different heterocyclic hydrazide derivatives is reported. The method involves the preparation of per-O-acetylated glycosyl isothiocyanates from per-O-acetylated sugars (two-step synthesis), which couple with heterocyclic hydrazides from amines to give thiourea-linked pseudonucleosides. All newly synthesized pseudonucleosides

medium, template), would provide an alternative approach to the de novo design of functional dynamic bio-macromolecules. As a first step towards this goal, various mono- and bifunctionalised (hetero- and homotopic) nucleic acid-derived building blocks of type I–X have been synthesised for the generation of dynamic main-chain and side-chain reversible nucleicacid analogues. Hydrazide- and/or acetal
