Electric Literature of C22H25NO9SOn October 31, 2000 ,《Synthesis of the key disaccharide of 3′-Sulfo Lewis X and Lewis A: the novel E-selectin ligand》 appeared in Synthetic Communications. The author of the article were Chowdhury, U. S.. The article conveys some information:
Benzyl 2,4,6-tri-O-benzyl-β-D-galactopyranoside (I) was synthesized from regioselective protection of stannylated benzyl 2,6-di-O-benzyl -β-D-galactopyranoside with 4-methoxybenzyl chloride, followed by benzylation and oxidative removal of the temporary protecting group. The disaccharide II was prepared by condensation of the common acceptor I and III through thiol activation as well as with IV following Konigs Knorr procedure. In the experiment, the researchers used many compounds, for example, Ethyl 3,4,6-tri-O-acetyl-2-deoxy-2-phthalimido-β-D-thioglucopyranoside(cas: 99409-32-2Electric Literature of C22H25NO9S)
Ethyl 3,4,6-tri-O-acetyl-2-deoxy-2-phthalimido-β-D-thioglucopyranoside(cas: 99409-32-2) belongs to indole.The indole subunit is an almost ubiquitous component of biologically active natural products, and its study has been the focus of research for decades.Electric Literature of C22H25NO9SThey are capable of binding to a variety of receptors with high affinity and thus have applications in a wide range of therapeutic areas. Due to this activity, the indole ring system has become an important component or intermediate in the synthesis of heterocycles.
