"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:** Predicting relative efficiency of amide bond formation using multivariate linear regression\n- **Authors:** Brittany C. Haas, Adam E. Goetz, Ana Bahamonde et al.\n- **Published:** PNAS, 2022-04-11\n- **DOI:** [10.1073/pnas.2118451119](https://doi.org/10.1073/pnas.2118451119)\n- **ORD wishlist card:** [open on GitHub](https://github.com/orgs/open-reaction-database/projects/11?pane=issue&itemId=126570043)\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 88 reactions; kinetic dataset): 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\nOpen-access article (PMC9169781, CC BY-NC-ND 4.0 article licence). It has two XLSX supplementary datasets and an SI Appendix PDF. Dataset S1 contains only DFT-descriptor PCA/clustering tables for the acids and amines. The reaction data are second-order rate constants k (M^-1 min^-1) for carboxylic acid + primary alkyl amine couplings with CDI in THF, ~88 combinations. They are expected in the SI Appendix and possibly in Dataset S2. Kinetics were followed by quenching unreacted amine with 2,4-dinitrofluorobenzene and quantifying by UPLC-PDA against 2,6-dinitrotoluene as internal standard. Each product was also isolated and characterised. Substrate structures may be available only as drawings or names, so SMILES may need to be generated.\n\nKnown locations:\n\n- [https://www.ebi.ac.uk/europepmc/webservices/rest/PMC9169781/fullTextXML](https://www.ebi.ac.uk/europepmc/webservices/rest/PMC9169781/fullTextXML): Full text (PMC9169781). Lists supplementary files pnas.2118451119.sd01.xlsx and sd02.xlsx. Data availability says all data are in the article/SI. (license: CC BY-NC-ND 4.0 (article licence per Crossref/OpenAlex; the SI licence is not separately stated))\n- [https://www.ebi.ac.uk/europepmc/webservices/rest/PMC9169781/supplementaryFiles](https://www.ebi.ac.uk/europepmc/webservices/rest/PMC9169781/supplementaryFiles): Europe PMC supplementary bundle (zip, partial download). Dataset S1 (sd01.xlsx, ~2.6 MB) has sheets 'Acid PCA & Clustering' and 'Amine PCA & Clustering' with DFT descriptor PCA loadings/clusters. It has no reaction outcomes and no SMILES column. (license: CC BY-NC-ND 4.0 (assumed from article))\n- [https://www.pnas.org/doi/suppl/10.1073/pnas.2118451119/suppl_file/pnas.2118451119.sd02.xlsx](https://www.pnas.org/doi/suppl/10.1073/pnas.2118451119/suppl_file/pnas.2118451119.sd02.xlsx): Dataset S2. Per the paper, DFT descriptors used for model generation. It may also carry the measured ln(k); not inspected. (license: CC BY-NC-ND 4.0 (assumed))\n- [https://www.pnas.org/doi/suppl/10.1073/pnas.2118451119/suppl_file/pnas.2118451119.sapp.pdf](https://www.pnas.org/doi/suppl/10.1073/pnas.2118451119/suppl_file/pnas.2118451119.sapp.pdf): SI Appendix PDF. Kinetic procedure, likely rate-constant tables, and characterisation of isolated products (pnas.org returned 403). (license: CC BY-NC-ND 4.0 (assumed))\n\n## Pitfalls\n\nOutcomes are rate constants, not yields. ORD has no native rate-constant field, so a convention is needed: a CUSTOM product measurement, or time-course amine consumption if timepoints are tabulated. Training and validation sets may be reported separately. The descriptor spreadsheets are not reaction data and should not be imported as reactions.\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",
