ortho-Methylphenylthioglycosides as glycosyl building blocks for preactivation-based oligosaccharide synthesis.

Highlights: [•] o-Methylphenylthioglycosides were used as blocks in preactivation protocol. [•] The aglycon transfer was avoided. [•] The efficiency of glycosyl coupling reactions was enhanced. [•] The thioglycosides were efficiently employed in one-pot oligosaccharide assembly. [ABSTRACT FROM AUTHOR]
