5,6-O-carbonyl-1,2-O-isopropylidene-3-O-tosyl-α-D-glucofuranose is a complex organic compound derived from α-D-glucofuranose, a monosaccharide. 5,6-O-carbonyl-1,2-O-isopropylidene-3-O-tosyl-α-D-glucofuranose is characterized by the presence of a carbonyl group at the 5,6 positions, an isopropylidene protecting group at the 1,2 positions, and a tosyl protecting group at the 3 position. The isopropylidene group shields the hydroxyl groups at positions 1 and 2, while the tosyl group protects the hydroxyl group at position 3. These protecting groups are crucial in organic synthesis as they prevent unwanted side reactions and allow for selective functionalization of the molecule. The compound is used in the synthesis of various complex carbohydrates and glycoconjugates, playing a significant role in the field of carbohydrate chemistry and biochemistry.

2818-57-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2818-57-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,1 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2818-57:
(6*2)+(5*8)+(4*1)+(3*8)+(2*5)+(1*7)=97
97 % 10 = 7
So 2818-57-7 is a valid CAS Registry Number.

Thio-sugars. I. Radical-promoted thione-thiol rearrangement of cyclic thionocarbonates: Synthesis of 5-thioglucose

Tsuda, Yoshisuke,Sato, Yoshiyuki,Kanemitsu, Kimihiro,Hosoi, Shinzo,Shibayama, Kenji,Nakao, Kayo,Ishikawa, Yuko

, p. 1465 - 1475 (2007/10/03)

The 5,6-O-thiocarbonyl-α-D-glucofuranose derivatives 2, when subjected to one of the following reactions, undergo a radical-promoted thione-thiol rearrangement to yield the 5-S-thiolcarbonates of gluco-configuration 8 as the major product. The reactions are, (A) thermolysis with a catalytic amount of tributyltin hydride and AIBN, (B) photolysis with hexabutyldistannane, and (C) thermolysis with dimethyl phosphonate and benzoyl peroxide. On the other hand, thermolysis of 2 with trialkylsilane (condition D) yielded olefins 13 as the major product. The 5-S-gluco product 8 was converted, in three steps, to 5-thioglucose (21) in 55% yield.
