Zhang, Yanxin; Zhang, Han; Zhao, Ying; Guo, Zhongwu; Gao, Jian published the artcile< Efficient Strategy for α-Selective Glycosidation of D-Glucosamine and Its Application to the Synthesis of a Bacterial Capsular Polysaccharide Repeating Unit Containing Multiple α-Linked GlcNAc Residues>, Formula: C11H15NO3, the main research area is stereoselective glycosylation catalyst aminoglycoside preparation disaccharide oligosaccharide.
An efficient α-selective glycosylation method was developed for the synthesis of 2-deoxy-2-amino-D-glucosides based on synergetic α-directing effects of the TolSCl/AgOTf promotion system and the functional groups at the corresponding azido donor 6-O-position to exert steric β-shielding effect or remote participation in the glycosylation reaction. Its practicability was verified with a wide range of monosaccharide glycosyl acceptors and the first, one-pot synthesis of the challenging pentasaccharide repeating unit of an Acinetobacter baumannii K47 capsular polysaccharide.
Organic Letters published new progress about Acinetobacter baumannii. 34637-22-4 belongs to class esters-buliding-blocks, and the molecular formula is C11H15NO3, Formula: C11H15NO3.
