5-Thio-L-idopyranose

Adley and Owen [3] described the synthesis of 5-thio-L-idopyranose 12 by the ring opening of 5,6-dideoxy-5,6-epithio-l,2-0-isopropyhdene-a-L-idofuranose 13, with potassium acetate in a mixture of glacial acetic acid and acetic anhydride and subsequent deprotection. 5-Thio-D-glucopyranose 10 was first synthesized by Feather and Whistler [8].
