    "statement_md": "# Curate this paper into an ORD dataset\n\nBuild an Open Reaction Database (ORD) dataset of the reactions reported in:\n\n- **Paper:** Preparation of 2-Heteroaryl-indolin-3-ones by Acid-Mediated Intramolecular Cyclization in Batch and Flow\n- **Authors:** Zeynep Saglam, Shu-Yu Liu, Yiding Chen et al.\n- **Published:** Org Lett, 2025-02-08\n- **DOI:** [10.1021/acs.orglett.5c00148](https://doi.org/10.1021/acs.orglett.5c00148)\n- **ORD wishlist card:** [open on GitHub](https://github.com/orgs/open-reaction-database/projects/11?pane=issue&itemId=126870725)\n\nThe reference input `card` holds these facts, the source-data locations and the notes below in machine-readable form.\n\n## Scope\n\nEvery reaction the paper reports with its data (the wishlist estimates about 21 reactions; DOE): inputs with amounts and roles, conditions, workups, outcomes and provenance, following the `ord-curation` Skill. Submit one ORD Dataset for the paper; if its data come from several screens or methods, keep them together and say so in the dataset description.\n\n## Source data\n\nSource: Saglam et al., Org. Lett. 2025, doi:10.1021/acs.orglett.5c00148. Acid-mediated intramolecular cyclisation to 2-heteroaryl-indolin-3-ones in batch and flow. The main target is a 21-run DOE campaign tabulated in the Supporting Information. The base, acid and solvent screens use a general method and can form a second dataset. The source has no SMILES, but few distinct species are involved, so assignment is quick. Record the DOE factor levels (e.g., temperature, equivalents, time, concentration) per run, and state which runs were batch and which were flow. The SI is ACS-hosted and not openly licensed. Cite it, but do not redistribute it.\n\nKnown locations:\n\n- [https://doi.org/10.1021/acs.orglett.5c00148](https://doi.org/10.1021/acs.orglett.5c00148): Org. Lett. article landing page and ACS-hosted SI PDF with the tabulated 21-run DOE and the base/acid/solvent screens (license: ACS publisher terms (closed article))\n\n## Pitfalls\n\nAny flow runs need flow-reactor representation (residence time, flow rates) in ORD, unlike the batch runs. The DOE response may be an assay yield or conversion by HPLC, whose method must be recorded. The screens and the DOE may be better split into two datasets.\n\n## Deliver\n\n- `dataset`: the ORD Dataset, compressed (`.binpb.gz`, `.pb.gz`, `.txtpb.gz`, `.pbtxt.gz` or `.parquet`), citing the DOI above in every reaction's provenance, with no dataset or reaction IDs.\n- `sources`: a `.zip` with a `README.md` (which tables or files each part came from, how structures were checked), the template and spreadsheet or the script or notebook that rebuild the dataset, and `validation.txt`, the output of ORD's validator (ord-schema 0.8.3) on the `dataset` file.\n\n## After starting your Attempt\n\nOpen the wishlist card and check other Attempts. If the work is completed or already well underway, record the reason before ending your Attempt as abandoned. Get the source data only through legitimate channels (the publisher's Supporting Information, the repositories above, or the authors). Submitting the finished dataset to ORD, and ORD's separate Dataset Rewards program, follow ORD's own rules.\n\n\n## Evaluation and public curator identity\n\nTFP first runs the pinned automatic ORD validator on the exact dataset file, then requires two independent agent reviews; both must pass. Review agents follow the required ord-curation Skill and review.md, use the published model policy, inspect primary sources and independently rebuild the result. Warnings and scientific ambiguities require review even when validation passes. ORD maintainers decide final acceptance separately.\n\nFor work commissioned by Tokens for Progress, use public curator name `Tokens for Progress` and email `hello@tokensforprogress.org`; independent contributors use their own confirmed public identity. Do not use reserved example email addresses or fabricate contact details. Include a source coverage manifest and disclose all unresolved data.\n",
