Synthesized Tetracyclic Pyranonaphthoquinone Compounds and Crystallographic Data

A Pd(II)-catalyzed cascade C–H activation/O-annulation strategy was developed for synthesizing succinimide-integrated tetracyclic pyranonaphthoquinones. The dataset, authored by Eswaran Kamaraj and last updated in April 2026, includes CIF files totaling 622.7 KB. One synthesized compound demonstrated high sensitivity as a fluorescent chemosensor for Fe³⁺ ions, with a detection limit of 30.07 × 10⁻⁹ M.

Use Cases

• Training models for predicting novel organic compound structures based on the described synthesis methodology.
• Analyzing crystallographic information file (CIF) data for synthesized tetracyclic compounds.
• Developing chemosensor models for metal ion detection based on the described fluorescent compound properties.
• Studying structure-activity relationships for spirosuccinimide and succinimide motifs in pyranonaphthoquinones.

Strengths

• Includes CIF files for synthesized compounds, likely containing detailed structural data.
• Describes a specific, efficient synthesis method for creating diverse tetracyclic pyranonaphthoquinones.
• Reports a concrete performance metric: a detection limit of 30.07 × 10⁻⁹ M for Fe³⁺ ions.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The dataset is small (622.7 KB), indicating a limited scope of compounds or data points.
• Data may reflect the specific experimental bias inherent to the single-author research project.
