A novel route using Schreiner thiourea mediated organocatalyzed [3+2] cycloaddition reaction of nitroolefins with diverse azides is devised to furnish high yield of 1,5-disubstituted 1,2,3-triazolyl glycoconjugates. The method has some notable features including metal-free, straightforward, acid-free, excellent regioselectivity operationally simple, wide substrate scope and high yielding. The Schreiner
