"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:** Nanoscale synthesis and affinity ranking\n- **Authors:** Nathan J. Gesmundo, Bérengère Sauvagnat, Patrick J. Curran et al.\n- **Published:** Nature, 2018-04-19\n- **DOI:** [10.1038/s41586-018-0056-8](https://doi.org/10.1038/s41586-018-0056-8)\n- **ORD wishlist card:** [open on GitHub](https://github.com/orgs/open-reaction-database/projects/11?pane=issue&itemId=126570092)\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: 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\nNanomole-scale (1536-well) Pd-catalysed coupling screens (Suzuki, C-N amination, amide/diverse nucleophile couplings) and library syntheses from Gesmundo et al., Nature 2018 (doi:10.1038/s41586-018-0056-8). Reaction data is in the article's Source Data Excel files (Fig. 2-4 and Extended Data Figs. 2-6, 8-10) on nature.com. Rows give reactant and product SMILES, plate position, catalyst (trade names such as XPhos Pd G3), base (e.g. P2-Et, BTMG, BTTP), solvent, LC-UV areas and a calculated percent yield from a product-to-internal-standard ratio. Reagent volumes are in the plate-map sheets. Concentrations, stoichiometry, temperature and time must be taken from the Supplementary Information PDF. Pitfalls: (1) some sheets identify building blocks only by MFCD number, so resolve SMILES from other sheets; (2) the 'Compiled Yield Data' sheet repeats rows from the individual screen sheets, so do not double-count; (3) some sheets have two yield columns (e.g. 'Calc. Percent Yield' and 'Calc'd % Yield Updated'), so state which one is used; (4) affinity-selection mass spectrometry (ASMS) binding data is not reaction data and is out of scope; (5) catalyst and base names need structures. The ORD Dataset must cite the paper DOI.\n\nKnown locations:\n\n- [https://www.nature.com/articles/s41586-018-0056-8](https://www.nature.com/articles/s41586-018-0056-8): Article landing page; lists the Supplementary Information PDF (MOESM1) and 11 Source Data files (Fig. 2, 3, 4; ED Fig. 2-6, 8-10) as XLS/XLSX (license: Springer Nature, closed-access article (Crossref: springer.com/tdm only))\n- [https://media.springernature.com/original/springer-static/esm/art%3A10.1038%2Fs41586-018-0056-8/MediaObjects/41586_2018_56_MOESM9_ESM.xlsx](https://media.springernature.com/original/springer-static/esm/art%3A10.1038%2Fs41586-018-0056-8/MediaObjects/41586_2018_56_MOESM9_ESM.xlsx): Source Data for ED Fig. 6 (catalyst/base survey, 0.78 MB).

Screens are spread across many sheets and files with overlap (compiled vs per-screen), so reviewers must check for deduplication. Many reactions give 0% yield (valid negative data). Precatalysts are named by trade name. Reaction conditions such as temperature, time and concentrations live in the SI PDF, not in the spreadsheets. It may need 2 datasets if library synthesis and condition screens are kept separate.\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",
