Sulfuric acid immobilized on silica: an efficient reusable catalyst for selective hydrolysis of the terminal O-isopropylidene group of sugar derivatives
Sulfuricacid immobilized on silica proved to be an efficientcatalyst for selective hydrolysis of the terminal O-isopropylidene group of sugar derivatives. The method is very simple and economic for large-scalesynthesis 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

A syntheticroute for the preparation of glucosylceramide synthase inhibitor N-[5-(adamantan-1-yl-methoxy)-pentyl]-1-deoxynojirimycin methanesulfonic acid salt (AMP-DNM) has been developed. Herein we report the development and optimization of this syntheticroute from its initial version in an academic research laboratory at milligram-scale to the final optimized route that was implemented in a cGMP
