Das, Saibal Kumar; Roy, Nirmolendu published their research in Carbohydrate Research on December 24 ,1996. The article was titled 《An improved method for the preparation of some ethyl 1-thioglycosides》.Electric Literature of C22H25NO9S The article contains the following contents:
Et 1-thioglycosides were prepared in almost quant. yield from sugar peracetates in 3:2 chloroform-ether, with boron trifluoride di-Et etherate as catalyst. D-Galactose, D-glucose, and 2-deoxy-2-phthalimido-D-glucose yielded almost exclusively β anomers, whereas L-rhamnose and D-mannose resulted predominantly in the α anomers. The experimental part of the paper was very detailed, including the reaction process of 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.
