A reliable and high yielding synthetic pathway for the synthesis of the biologically highly important class of nucleosidediphosphate sugars (NDP‐sugars) was developed by using various cycloSal‐nucleotides 1 and 9 as active ester building blocks. The reaction with anomerically pure pyranosyl‐1‐phosphates 2 led to the target NDP‐sugars 20–45 in a nucleophilic displacement reaction, which cleaves the

Succinyl‐cycloSal‐phosphate triesters of ribo‐ and 2′‐deoxyribonucleosides were attached to aminomethyl polystyrene as an insoluble solid support and reacted with phosphate‐containing nucleophiles yielding nucleoside di‐ and triphosphates, nucleoside diphosphate sugars, and dinucleoside polyphosphates in high purity after cleavage from the solid support. Here, reactive cycloSal‐phosphate triesters were
