SDS of cas: 99409-32-2On May 31, 2005, Hou, Shu Jie; Zou, Chuan Chun; Lei, Ping Sheng; Yu, De Quan published an article in Chinese Chemical Letters. The article was 《An efficient way for glycosylation of spirostanol》. The article mentions the following:
Using thioglycosides as donors and trimethylsilyl trifluoromethanesulfonate (TMSOTf) and N-iodosuccinimide (NIS) as promoter, a modified procedure for the glycosylation of spirostanols was developed. A series of saponins were synthesized in mild condition with excellent yields. E.g., sapogenin glucoside I (R = phthalimido) was prepared with quant. yield by reacting diosgenin with Et 3,4,6-tri-O-acetyl-2-deoxy-2-phthalimido-1-thio-β-D-glucopyranoside using TMSOTf, NIS and 4Å mol. sieves in CH2Cl2 at -15°. In the experimental materials used by the author, we found Ethyl 3,4,6-tri-O-acetyl-2-deoxy-2-phthalimido-β-D-thioglucopyranoside(cas: 99409-32-2SDS of cas: 99409-32-2)
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.SDS of cas: 99409-32-2They 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.
