  "notes": "Paper: Wang et al., Nat. Commun. 2023, 14, doi:10.1038/s41467-023-43614-3, CC BY 4.0. It describes a 384-well nanoscale plate built around a pomalidomide-derived isocyanide. Wells A1-F8 are Ugi-4CR (amine, aldehyde/ketone, carboxylic acid, isocyanide). Wells F9-K16 are Ugi with aqueous formaldehyde as the oxo component. Wells K17-P24 are Ugi-tetrazole (amine, oxo component, isocyanide, TMSN3, 2.4 equiv). Building blocks were dispensed by I.DOT as 0.5 M TFE stocks (isocyanide 0.25 M, TMSN3 0.6 M). Each well was analysed by direct-injection MS and classified as major product (the [M+H], [M+Na] or [M+K] peak is the highest), no product (peak absent), or medium product (otherwise). The Fig. 4A heatmap source data should be in 'source data in manuscript.xlsx' inside the Source Data zip (MOESM3; the zip is about 377 MB, so download selectively). Raw Waters MassLynx .raw folders are provided for every well. Building-block identities are in the SI PDF (MOESM1, including Supplementary Table 1 for the isocyanide) and need converting to SMILES. The biology data (proteomics, viability, western blots) is out of scope.",
  "verification_caveats": "Outcomes are qualitative (three classes) with no yields, so they must be encoded carefully, for example as product identity plus a custom or qualitative measurement. Three reaction templates share one plate. This is direct-to-biology synthesis with no purification. Products are implied rather than characterized, apart from a few resynthesized hits. The well-to-building-block mapping must be reconstructed from the SI plate layout."
