4782-99-4

3,4-O-Isopropyliden-β-D-arabinopyranosid is a chemical compound derived from the sugar arabinose, specifically a β-D-arabinopyranosid. It is characterized by the presence of an isopropylidene group, which is a three-carbon chain with two methyl groups and one hydrogen atom, attached to the 3 and 4 hydroxyl groups of the arabinopyranosid ring. This modification provides protection to the hydroxyl groups, which is crucial in organic synthesis, particularly in the preparation of complex carbohydrates and other biologically active molecules. The compound is often used in the synthesis of various pharmaceuticals and natural products due to its ability to stabilize the sugar structure and prevent unwanted side reactions. Its unique structure also makes it a valuable intermediate in the preparation of other arabinose derivatives, contributing to the development of new drugs and materials in the fields of chemistry and biology.

4782-99-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4782-99-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,8 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4782-99:
(6*4)+(5*7)+(4*8)+(3*2)+(2*9)+(1*9)=124
124 % 10 = 4
So 4782-99-4 is a valid CAS Registry Number.

Absolute stereostructures of betavulgarosides III and IV, inhibitors of glucose absorption, from the roots of Beta vulgaris L. (sugar beet)

Yoshikawa, Masayuki,Murakami, Toshiyuki,Inaduki, Masahiro,Hirano, Kazuhiro,Yamahara, Johji,Matsuda, Hisashi

, p. 561 - 563 (1997)

The absolute stereostructures of betavulgarosides III and IV, which were isolated from the roots of Beta vulgaris L. (sugar beet) and exhibited inhibitory activity on glucose absorption, were determined by the chemical correlation of betavulgaroside IV with a known saponin momordin I, which included the conversion from the α-L-arabinopyranosyl moiety of momordin I to the acidic acetal-type substituent of betavulgarosides III and IV via the α-L-ribopyranosyl derivative. Furthermore, four acidic acetal-type substituent analogues were synthesized from L- and D-arabinose.

Medicinal foodstuffs. XVI. Sugar beet. (3): Absolute stereostructures of betavulgarosides II and IV, hypoglycemic saponins having a unique substituent, from the roots of Beta vulgaris L.

Murakami, Toshiyuki,Matsuda, Hisashi,Inadzuki, Masahiro,Hirano, Kazuhiro,Yoshikawa, Masayuki

, p. 1717 - 1724 (2007/10/03)

The absolute stereostructures of betavulgaroside II having a dioxolane- type substituent and betavulgaroside IV having an acetal-type substituent, which were isolated from the roots of Beta vulgaris L. (sugar beet, Chenopodiaceae) and exhibited hypoglycemic activity on glucose-loaded rats, were determined by the chemical correlations of betavulgarosides II and IV with a known saponin, momordin I. In these chemical correlations, the α-L- arabinopyranosyl moiety of momordin I was converted to a dioxolane-type substituent of betavulgaroside II or to an acetal-type substituent of betavulgaroside IV. Additionally, the 2'-diastereoisomer of betavulgaroside IV was synthesized from momordin I, and four acetal-type substituent analogues were also synthesized from L- and D-arabinose.
