Synthetic Data for 3-Arylquinoxaline-2-Ones via Annulative Coupling

A 28.7 MB dataset from figshare details a p-TSA-promoted annulative coupling method for synthesizing 3-arylquinoxalin-2-ones. The protocol, published by Trayambek Nath Chaubey in May 2026, proceeds under metal-free conditions and features broad functional group tolerance. Its practicality is demonstrated by gram-scale synthesis and late-stage functionalization examples.

Use Cases

• Predicting reaction yields based on described functional group tolerance and reaction conditions.
• Training models to identify viable diazo ester and diamine partners for quinoxaline synthesis.
• Generating synthetic pathways for bioactive molecule precursors based on described late-stage functionalization steps.
• Benchmarking computational methods against experimental data from gram-scale synthesis demonstrations.

Strengths

• Dataset size is 28.7 MB, indicating a substantial amount of structured information.
• The description details a specific, metal-free synthetic protocol with demonstrated gram-scale application.
• Late-stage functionalization examples, including triflation and Sonogashira coupling, are provided.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale ML tasks.
• The 28.7 MB file size suggests a small to moderate dataset scale.
