Description

5H-1,3-Dioxolo[4,5-c]pyrrole-5-carboxylic acid, 4-(4,5-dihydro-4-oxo-1H-pyrrolo[3,2-d]pyrimidin-7-yl)tetrahydro-2,2,6-trimethyl-, 1,1-dimethylethyl ester, (3aS,4S,6R,6aR)- is a sophisticated, high-purity pharmaceutical intermediate characterized by its complex heterocyclic structure. This compound is critical for the synthesis of advanced active pharmaceutical ingredients (APIs), where its specific stereochemistry and functional groups enable precise molecular construction. It is primarily utilized by research institutions and pharmaceutical manufacturers engaged in the development of novel therapeutic agents, particularly in oncology and antiviral research.

Application

• Pharmaceutical Intermediate: A key building block in the multi-step synthesis of complex drug candidates and active pharmaceutical ingredients (APIs).
• Oncology Research: Used in the development of targeted cancer therapies due to its pyrrolopyrimidine core, a common pharmacophore in kinase inhibitors.
• Antiviral Drug Development: Serves as a precursor in the synthesis of nucleoside/nucleotide analogs for antiviral applications.
• Process Chemistry & Scale-Up: Employed in route scouting, optimization, and pilot-scale production for new chemical entities (NCEs).
• Contract Manufacturing (CMO/CDMO): Supplied to contract research and manufacturing organizations for cGMP-compliant production.
• Academic & Industrial R&D: Used in medicinal chemistry programs for structure-activity relationship (SAR) studies and lead optimization.
