Carbocyclic Sinefungin.

Area of Science:

• Organic Chemistry
• Medicinal Chemistry
• Synthetic Chemistry

Background:

• Carbocyclic sinefungin is a potent inhibitor of S-adenosylhomocysteine hydrolase.
• Previous synthetic routes to carbocyclic sinefungin and its analogs are often lengthy and complex.
• Developing efficient and adaptable synthetic strategies is crucial for exploring structure-activity relationships.

Purpose of the Study:

• To establish a streamlined and adaptable synthetic route to carbocyclic sinefungin.
• To demonstrate the utility of a readily available ribose-derived intermediate for this synthesis.
• To enable the preparation of diverse carbocyclic sinefungin analogs.

Main Methods:

• An 18-step synthesis was designed starting from (3aS,4S,6R,6aR)-Tetrahydro-2,2-dimethyl-6-vinyl-3aH-cyclopenta[d][1,3]-dioxol-4-ol, a derivative of ribose.
• The synthetic strategy focused on efficient construction of the carbocyclic core and introduction of the sinefungin side chain.
• Adaptability of the method was assessed by exploring variations in the heterocyclic base and amino acid side chain.

Main Results:

• The 18-step preparation of carbocyclic sinefungin was successfully achieved.
• The ribose-derived starting material proved to be a convenient and effective entry point.
• The synthetic procedure demonstrated adaptability for generating analogs with modified heterocyclic bases and side chains.

Conclusions:

• A practical and adaptable 18-step synthesis for carbocyclic sinefungin has been established.
• This method provides a valuable platform for the synthesis of novel carbocyclic sinefungin analogs.
• The developed route facilitates further investigation into the medicinal properties of sinefungin derivatives.
