摘要
Thioacetalization of acyl protected furanosides led to products with an ethanethiol group at C-2 and 3-O-acetyl-1,2-di-O-isopropylidene-D-furanoses were converted into corresponding thioacetals with two ethanethiol groups at both C-2 and C-3 positions under the standard thioacetalization conditions. All products were characterized by H-1 NMR, C-13 NMR and HRMS data. X-ray structure analysis indicates that the vicinal acyloxy group is stereoselectively substituted by ethanethiols. The supposed mechanisms for these two kinds of transformations were presented.
