Category: isothiazole. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Weldu, WD; Wang, CC. The CAS is 93-97-0. Through research, I have a further understanding and discovery of Benzoic anhydride
Selective modification of the hydroxyl groups of sugars has been a long-standing challenge due to their proximate relative reactivity. Herein, we report a TMSOTf-catalyzed selective acetylation of the non-anomeric hydroxyl groups of several per-O-TMS-protected sugar substrates while leaving their anomeric group unaffected. In addition to standing versatile by itself, the anomeric O-TMS group left intact can be functionalized to afford key sugar precursors such as imidate donors, which could otherwise be synthesized via a stepwise anomeric deprotection-functionalization procedure.
