Propargyl Uridine-Based Synthesis of Glycosylated RNA Analogues
Abstract
We report a click chemistry strategy for synthesizing N3-triazole- and 2′-O-triazole-substituted glycosylated uridines and RNA oligonucleotides from N3-propargyl and 2′-O-propargyl uridines. Using β-D-glucopyranosyl azide, site-selective glycosylation was achieved at nucleoside and oligonucleotide levels, providing defined glycoRNA mimics for structural and functional studies.
