Access to α-glycosyl azides in modest to high diastereoselectivity by way of TMSN3 ring-opening of 1,6-anhydro sugars mediated by TMSOTf is reported. The reaction tolerates a wide variety of functional groups including alcohol, alkyne,
据报道,通过 TMSOTf 介导的 1,6-脱水糖的 TMSN3 开环,以中等至高的非对映选择性获得 α-糖基叠氮化物。该反应耐受多种官能团,包括醇、炔、
