The author of 《Iodonium ion-promoted reactions at the anomeric center. II. An efficient thioglycoside-mediated approach toward the formation of 1,2-trans-linked glycosides and glycosidic esters》 were Veeneman, G. H.; Van Leeuwen, S. H.; Van Boom, J. H.. And the article was published in Tetrahedron Letters in 1990. Category: indole-building-block The author mentioned the following in the article:
N-Iodosuccinimide (I) in the presence of an organic acid was effective for the activation of fully acylated thioglycosides leading to 1,2-trans linked esters. For example, tetrabenzoylthiogalactopyranoside II (R = EtS) was treated with I and MeOCH2CO2H in Et2O-ClCH2CH2Cl to give 98% II (R = MeOCH2CO2). On the other hand, I together with a catalytic amount of trifluoromethanesulfonic acid was very convenient for the rapid, high-yielding and stereoselective (1,2-trans) glycosidation of esterified thioglycosides with glycosyl acceptors, e.g., III, to give title compds, e.g., IV.Ethyl 3,4,6-tri-O-acetyl-2-deoxy-2-phthalimido-β-D-thioglucopyranoside(cas: 99409-32-2Category: indole-building-block) was used in this study.
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.Category: indole-building-blockThey are capable of binding to a variety of receptors with high affinity and thus have applications in a wide range of therapeutic areas.
