Abstract

1, MeOH-cat. 2, Ac2O-pyridine cy-aiid p-forms 11 HBr-HOAr In, K= I1+ attractive by the work of Letnieux who showed that the carbon-1 p-acetoxy group of an acetylated glucose is subject to displacement by an alkoxy1 group in the presence of stannic chloride. Thus, 1, 2, 3, 4-tetra-0-acetyl-PD-glucopyranose was converted into tri-O-acetyl-1, 6-anhydro-~-~- glucopyranose in 36y0 yieldllb and penta-0-acetyl-PD-glucopyranose into methyl tetra-0- ...
