# Curate this paper into an ORD dataset

Build an Open Reaction Database (ORD) dataset of the reactions reported in:

- **Paper:** Van Leusen Imidazole Synthesis for One-Bead-One-Compound DNA-Encoded Libraries
- **Authors:** Yihui Xie, Min-Chi Huang, Yanfen Jiang et al.
- **Published:** Bioconjugate Chemistry, 2025-08-23
- **DOI:** [10.1021/acs.bioconjchem.5c00317](https://doi.org/10.1021/acs.bioconjchem.5c00317)
- **ORD wishlist card:** [open on GitHub](https://github.com/orgs/open-reaction-database/projects/11?pane=issue&itemId=126616690)

The reference input `card` holds these facts, the source-data locations and the notes below in machine-readable form.

## Scope

Every reaction the paper reports with its data (the wishlist estimates about 300 reactions; DNA encoded library): 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.

## Source data

Van Leusen imidazole synthesis (TosMIC chemistry) adapted to one-bead-one-compound DNA-encoded libraries (WuXi AppTec). About 300 reactions are reported in SI tables. Building blocks are drawn as structure images, not given as names or SMILES, so an agent needs optical structure recognition or manual transcription. The article is closed access; the SI is typically downloadable from the publisher page (verify). If the authors can provide the table data in a structured format, extraction effort drops sharply. Cite DOI 10.1021/acs.bioconjchem.5c00317.

Not fetched because ACS blocks automated access. Europe PMC indexes it with no OA copy or supplement (license: ACS standard (Crossref TDM policy links only))

## Pitfalls

Substrates are DNA- and bead-conjugated, so the full conjugate cannot be expressed as a simple SMILES. The dataset needs a convention: the small-molecule portion with a documented attachment/linker placeholder, or ORD identifiers of type NAME/CUSTOM. Outcomes are likely LC-MS conversion percentages on DNA, not isolated yields. There may be multiple building-block classes (aldehydes, amines, TosMIC reagents) within one template.

## Deliver

- `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.
- `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.

## After starting your Attempt

Open 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.


## Evaluation and public curator identity

TFP 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.

For 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.
