Frame‐Shifted Synthesis of Oligoheterocycles as a Platform for Molecular Design
Bibliographic record
Abstract
Chemists continue to develop strategies that leverage abundant feedstocks to accelerate the production of medicines, agrochemicals, and materials. Oligoheterocycles are a broad class of molecules that span these disciplines. Cross-coupling strategies are commonly used to assemble oligoheterocycles; however, these methods can be challenging and often rely on precious metal catalysts and building blocks whose production entails significant environmental and economic costs. We present a strategy for the iterative construction of oligoheterocycles that leverages sustainable building blocks designed around high-oxidation-state carbon. By utilizing feedstocks from the base of the chemical supply chain, we generate bifunctional building blocks that chemoselectively engage with a variety of partners through simple condensation manifolds. This approach has enabled the creation of novel scaffolds previously inaccessible by conventional means, exemplifying sustainable design strategies.

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.
