Palladium-catalyzed carbonylation of halo arene-cis-dihydrodiols to the corresponding carboxylates. Access to compounds unavailable by toluene dioxygenase-mediated dihydroxylation of the corresponding benzoate esters
Bibliographic record
Abstract
A series of arene-cis-dihydrodiol carboxylates was prepared by palladium-catalyzed carbonylation of (1S, 2S-cis)-3-iodo-3,5-cyclohexadiene-1,2-diol, which is obtained in high titers by enzymatic dihydroxylation of iodobenzene. Both the free diol and the corresponding acetonide were subjected to this protocol to produce various arene-cis-dihydrodiol carboxylates that are unavailable by fermentation of the corresponding benzoates or are produced in low yields. The comparison of yields obtained from fermentation versus carbonylation was made for all compounds investigated. Experimental and spectral data are provided for all new compounds.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
