β-D-Arabinosyl 1-C-sulfonic acid

Area of Science:

• Carbohydrate Chemistry
• Organic Synthesis
• Biomimetic Chemistry

Background:

• Anomeric phosphates are crucial in biological systems.
• Developing stable biomimetics is essential for studying carbohydrate-related biological processes.
• Existing synthetic routes may lack efficiency or stability.

Purpose of the Study:

• To establish a concise synthetic pathway for β,d-arabinofuranosyl 1-C-sulfonic acid.
• To create a stable biomimetic analog of arabinofuranosyl anomeric phosphate.
• To demonstrate the feasibility of DMDO oxidation for C-sulfonate synthesis.

Main Methods:

• Synthesis of an S-acetyl-1-thio-β-arabinofuranose derivative.
• Buffered Dimethyldioxirane (DMDO) oxidation of the thio-sugar precursor.
• Mild deprotection conditions for the final sulfonic acid isolation.

Main Results:

• Successfully synthesized β,d-arabinofuranosyl 1-C-sulfonic acid (7) via a short route.
• The DMDO oxidation provided the furanosyl 1-C-sulfonate intermediate efficiently.
• Isolation of the free sulfonic acid was achieved without desulfonylation, confirming stability.

Conclusions:

• A practical and short synthetic route to β,d-arabinofuranosyl 1-C-sulfonic acid has been developed.
• This compound serves as a valuable and stable biomimetic for arabinofuranosyl anomeric phosphates.
• The synthetic strategy highlights the utility of DMDO oxidation in carbohydrate C-sulfonate synthesis.
