Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme. Irreversible inhibitors are therefore the equivalent of poisons in heterogeneous catalysis. 74808-09-6, C36H36Cl3NO6. A document type is Article, introducing its new discovery., name: (2R,3R,4S,5R,6R)-3,4,5-Tris(benzyloxy)-6-((benzyloxy)methyl)tetrahydro-2H-pyran-2-yl 2,2,2-trichloroacetimidate

The glycosyl trichloroacetimidates 1-alpha,beta, 8-alpha, 11-alpha, 13-alpha, 15-alpha, and 17-alpha directly transfer the glycosyl moiety to phosphoric acid mono- and diesters.The acidity of the phosphoric acid derivatives used was sufficient for the activation of the trichloroacetimidates, therefore an additional acidic catalyst was not required.From the beta-imidate 1-beta alpha-glycosyl phosphate and from the alpha-imidates preferentially beta-glycosyl phosphates were obtained.Reaction of dibenzyl phosphate (2a) and cetyl phosphate (2c) with 1-alpha demonstrated that beta/alpha-anomerization iscatalyzed by traces of acid.The glycosyl phosphates 3a-alpha, 3a-beta – 3c-beta, 3f-alpha, 9a-beta, and 9c-beta were partly or totally deprotected.The structures of the synthezised compounds were assigned by 1H NMR spectroscopy and by comparison with literature data.

Hypervalent azido- and cyanosilicate derivatives, prepared in situ by the reaction of trimethylsilyl azide or trimethylsilyl cyanide, respectively, with tetrabutylammonium fluoride, are effective sources of nucleophilic azide or cyanide. Primary and secondary alkyl halides and sulfonates undergo rapid and efficient azide or cyanide displacement in the absence of phase transfer catalysts with the silicate derivatives. Application of these reagents to the stereoselective synthesis of glycosyl azide derivatives is reported.
