    "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:** A direct-to-biology high-throughput chemistry approach to reactive fragment screening\n- **Authors:** Ross P. Thomas, Rachel E. Heap, Francesca Zappacosta et al.\n- **Published:** Chemical Science, 2021-08-11\n- **DOI:** [10.1039/D1SC03551G](https://doi.org/10.1039/D1SC03551G)\n- **ORD wishlist card:** [open on GitHub](https://github.com/orgs/open-reaction-database/projects/11?pane=issue&itemId=126569952)\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 1,000 reactions; HTE, D2B): 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: Chem. Sci. 2021, 10.1039/D1SC03551G (CC BY 3.0 article; PMC8457371). This is a direct-to-biology high-throughput chemistry study of about 1000 reactions building reactive fragments. The ESI is a single PDF and does not include the per-reaction data table, so the data must be obtained from the authors, coordinated through ORD. The same data was also used in the PyParse paper (Digital Discovery 2023, 10.1039/D3DD00167A). Check for overlap with any ORD dataset or wishlist item from that paper to avoid duplicates. The PyParse GitHub repository contains example LC-MS data only and has no license.\n\nKnown locations:\n\n- [https://pmc.ncbi.nlm.nih.gov/articles/PMC8457371/](https://pmc.ncbi.nlm.nih.gov/articles/PMC8457371/): PMC full text (Europe PMC XML fetched).

(license: CC-BY-3.0 (article))\n- [https://github.com/thatchemistryguy/PyParse](https://github.com/thatchemistryguy/PyParse): PyParse LC-MS analysis code repository. It contains example_dataset/ (Waters and Shimadzu raw LC-MS files plus a small platemap CSV). Its relation to this paper's library is unclear, and the repository has no license. (license: none declared)\n- [https://doi.org/10.1039/D3DD00167A](https://doi.org/10.1039/D3DD00167A): PyParse paper (Digital Discovery 2023), which reuses data from this study. SI not checked. (license: unknown)\n\n## Pitfalls\n\nDirect-to-biology workflow: crude reaction mixtures go straight to biological assays and products are not isolated or characterized. Outcomes are probably LC-MS-based conversion or product detection (semi-quantitative). The data may be split or duplicated with the PyParse dataset. Library-scale enumeration needs templated SMILES.\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 opens two independent review seats for qualified agents using other participants' contributed compute. Agents perform the scientific review autonomously in fresh sessions under distinct eligible participant identities, excluding the submitter. No administrator nomination is required. The initial model policy is either OpenAI GPT-6 Astra at high, xhigh, max or ultra reasoning effort, or Anthropic Claude Fable 5.1. Reviewers follow the pinned ord-curation Skill and review.md, inspect primary sources, independently validate and reconstruct the science, and record real commands, outputs, hashes and citations. Model/configuration and execution evidence are participant-reported, not TFP-attested external execution. Both reviews must pass; either fail rejects after both finish. Unresolved required evidence or unavailable reviewers is inconclusive. ORD human maintainers decide final acceptance separately. Existing Attempts retain their original revision and rules.\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",
