2-C-Methyl-D-ribono-1,4-lactone丨CAS 492-30-8

1. Key Intermediate in Nucleoside and Antiviral Synthesis

2-C-Methyl-D-ribono-1,4-lactone is a critical building block in the synthesis of modified nucleosides and nucleotide analogs, many of which are used as antiviral and anticancer agents.

It is especially important in the synthesis of:

Sofosbuvir (an HCV antiviral drug)

Ribavirin derivatives

Modified nucleosides for RNA-dependent RNA polymerase inhibitors

The methyl substitution at the 2-position makes it useful for synthesizing C-methylated sugar moieties, a feature that improves the metabolic stability and potency of many antiviral compounds.

2. Starting Material for C-Nucleoside Synthesis

C-nucleosides differ from regular nucleosides in that the sugar and base are linked through a carbon-carbon (C–C) bond instead of a glycosidic (C–N or C–O) bond.

These structures offer greater resistance to enzymatic cleavage, making them more durable in biological systems.

2-C-Methyl-D-ribono-1,4-lactone is frequently employed to construct the sugar portion in these C-nucleosides due to its structural rigidity and ease of derivatization.

3. Chiral Intermediate in Organic Synthesis

Its multiple stereocenters and lactone functionality make it an ideal chiral starting material in asymmetric synthesis.

Can be used to generate a wide range of chiral molecules with biological activity, such as:

Heterocycles

Polyhydroxylated compounds

Sugar analogs

4. Research in Carbohydrate and Nucleic Acid Chemistry

Extensively used in academic and industrial research to study:

Sugar conformations

Nucleotide analog development

Mechanisms of action for antiviral drugs

Also useful in enzymatic transformation studies and glycosylation reactions.

1. High Selectivity and Functional Versatility

The methyl group at C-2 creates regioselectivity and stereoselectivity in downstream reactions, which simplifies synthesis of targeted bioactive compounds.

Its lactone ring can be easily opened under mild conditions, offering access to various open-chain sugar acids.

2. Improved Bioactivity in Final Compounds

Derivatives of 2-C-methyl sugars often display enhanced biological properties, including:

Improved pharmacokinetics

Greater cell permeability

Increased resistance to degradation

These traits are vital for drug candidates targeting viral enzymes like RNA polymerases.

3. Commercially Available and Scalable

The compound is available in high purity from multiple chemical suppliers.

It is scalable, making it suitable for both laboratory-scale synthesis and industrial drug production.

4. Environmentally Friendly

Being a sugar derivative, it is typically non-toxic, biodegradable, and derived from renewable resources.

Its use contributes to more green chemistry approaches in pharmaceutical manufacturing.
