A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 74808-09-6, Name is (2R,3R,4S,5R,6R)-3,4,5-Tris(benzyloxy)-6-((benzyloxy)methyl)tetrahydro-2H-pyran-2-yl 2,2,2-trichloroacetimidate, molecular formula is C36H36Cl3NO6. In a Article，once mentioned of 74808-09-6, Computed Properties of C36H36Cl3NO6
A novel and efficient glycosyl donor having a p- trifluoromethylbenzylthio-N-p-trifluoromethylphenylformimidate group at an anomeric position is easily prepared by the addition of anomeric hydroxy group of 2,3,4,6-tetra-O-benzyl-alpha,beta-D-glucopyranose to p-trifluoromethylphenyl isothiocyanate, followed by treatment with p-trifluoromethylbenzyl bromide. Catalytic and stereoselective glycosylation of various glycosyl acceptors with the above glycosyl donor smoothly proceeds by using various protic and Lewis acid catalysts which interact with its nitrogen atom. Further, catalytic and highly 1,2-cis or 1,2-trans stereoselective and chemoselective glycosylation between two different “armed” and “disarmed” glycosyl p- trifluoromethylbenzylthio-N-p-trifluoromethylphenylformimidates is also performed effectively in the presence of a catalytic amount of trifluoromethanesulfonic acid (TfOH) at -78 C in tBuOMe or EtCN, respectively. These glycosylations are applied to successful one-pot sequential syntheses of trisaccharides.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Computed Properties of C36H36Cl3NO6, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 74808-09-6, in my other articles.
