Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps. 73464-50-3, Name is (2R,3R,4S,5S,6S)-2-Hydroxy-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate, molecular formula is C13H18O10. In a Article,once mentioned of 73464-50-3, Synthetic Route of 73464-50-3
A simple, regioselective O-deacetylation procedure is described which involves =0.5 equiv. of Bu3SnOMe or Bu2SnO in methanol.Anomeric acetates are considerably more reactive than primary and secondary acetates, thereby enabling selective removal, to give ca.70percent of products with HO-1 unsubstituted.Prolonged reaction resulted in complete deacetylation.Secondary acetates were removed faster than primary acetates and the overall rates of reaction were influenced greatly by the anomeric substituent in the order of OAc >> OH > OMe.No acyl migration took place under the reaction conditions.
