OSCAR: an extensive repository of chemically and functionally diverse organocatalysts

Abstract: The automated construction of datasets has become increasingly relevant in computational chemistry. While transition-metal catalysis has greatly benefitted from bottom-up or top-down strategies for the curation of organometallic complexes libraries,...

“…While a large scope for catalyst modularity can be construed as a possible limitation, it is evident that catalyst optimization requires some level of structural feature tuning. Indeed, H-bonding catalysts like thioureas and cinchona alkaloids have multiple points for introducing a broad set of groups encompassing different steric and electronic properties . In contrast, secondary amines have witnessed significantly less structural diversity at the chiral framework.…”

“…Indeed, Hbonding catalysts like thioureas and cinchona alkaloids have multiple points for introducing a broad set of groups encompassing different steric and electronic properties. 27 In contrast, secondary amines have witnessed significantly less structural diversity at the chiral framework. This can be demonstrated by the number of unique catalysts present in the database that correspond to a particular chemotype.…”

“…32,33 While the latter type of descriptor is readily calculable with cheminformatics packages in milliseconds, the computational cost of deriving descriptors from DFT calculations can be significant and render these workflows inaccessible or impractical for many researchers. Efforts like kraken 34 and OSCAR 35 seek to precompute and/or predict descriptor values for hundreds, thousands, or even millions of hypothetical ligands or catalysts.…”

“…A high-throughput computational workow begins populating the database with DFT computational data. Similar data structures involving high-throughput computation for pconjugated organic molecules exist, [25][26][27][28][29][30] and there also exist databases targeting batteries. 19,31,32 But unlike these existing databases, D 3 TaLES provides a data infrastructure and framework for multiple data types targeting NARFB.…”
