, p. 430 - 431 (2001)
A facile chemoselective hydrolysis of terminal isopropylidene acetals has been achieved using a catalytic amount of Yb(OTf)3·H2O in acetonitrile at ambient temperature.
Sulfuric acid immobilized on silica: an efficient reusable catalyst for selective hydrolysis of the terminal O-isopropylidene group of sugar derivatives
Rajput, Vishal Kumar,Roy, Bimalendu,Mukhopadhyay, Balaram
, p. 6987 - 6991 (2006)
Sulfuric acid immobilized on silica proved to be an efficient catalyst for selective hydrolysis of the terminal O-isopropylidene group of sugar derivatives. The method is very simple and economic for large-scale synthesis in which the catalyst is recovered and reused for several runs. Reactions with di-O-isopropylidene derivatives of d-glucose, d-mannose, d-fructose and l-sorbose led to the formation of the corresponding mono-O-isopropylidene derivatives in good to excellent yields.

scheme or table, p. 79 - 86 (2012/07/28)
Two series of imidazo[2,1-b]thiazoles substituted on C-3 or C-5 with an unprotected carbohydrate moiety were synthesized. Different protective groups for position 3 of the carbohydrate moiety were tested (acetyl, tert-butyldimethylsilyl (TBDMS), and p-met
