摘要:In one aspect, the disclosure relates to a facile strategy to introduce electron-deficient aryl sulfate diesters to silylated hydroxyl groups of carbohydrates and amino acids, among other substrates, wherein selective hydrolysis and the removal of an electron-deficient aromatic group allows for the efficient generation of sulfated carbohydrates, peptides, and other compounds. The incorporation of electron-deficient aryl sulfate diesters in the early stage of the synthesis of glycans, peptides, and the like, disclosed herein avoids time-consuming protecting group manipulations, simplifies the purification of sulfated products, and improves the overall yield and efficiency. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

摘要:The disclosure provides a chemical synthesis method for a disaccharide fragment of a Vibrio vulnificus biotype 2 serovar A O-antigen, belonging to the chemical field. The disclosure utilizes D-glucose and L-galactose as raw materials to prepare two types of glycosylated building blocks, and designs an efficient synthesis route for constructing the disaccharide fragment. By optimizing protecting groups and optimizing the time of introducing modifying groups, the preparation of the target disaccharide is successfully completed. The raw materials for preparing the disaccharide in the disclosure are readily available, the preparation method is simple and easy to repeat, and will have a good application prospect in the development of new drugs and vaccines for V. vulnificus.
