Bifunctional Resins Applications to the Synthesis of Insect Sex Attractants
Bibliographic record
Abstract
A 2f crosslinked divinylbenzene-styrene copolymer, incorporating benzoyl chloride groups, was used to monoprotect the symmetrical diol l,l0-decanediol.The corresponding monotrityl ether and cir-10-tetradecenJ-ol were prepared by this system, the latter by a Wittig reaction of a polymer-bound ylide with an aldehyde in the solution phase.A series of bifunctionalized resins containing proximally located trityl alcohol and benzoic acid groups was prepared in an attempt to prepare diol linked to the polymer via both a trityl ether and a benzoate linkage.It was established that these polymers bound l,l0-decanediol exclusively at one end only.Polymers, containing both trityl alcohol and benzoic acid groups in a random array or polymers containing proximally located trityl alcohol groups, gave mixtures of both monoprotected and doubly protected diol.Txomes M.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
