资源简介：
A synthesis of the branched tetrasaccharide fragment of saccharomicin A using 1-OTBS donors to stereoselectively synthesize both α- and β-linked disaccharides is reported. The disaccharides were united using BSP/Tf2O to afford the tetrasaccharide fragment as a single α-anomer in 72% yield. This branched tetrasaccharide fragment can be used as donor and acceptor species to synthesize larger fragments of saccharomicin A.
