Enantioselective Hydrogenation of N-H Imines
Bibliographic record
Abstract
A) Preparation and Physical Data for N-H imines Hydrochloride S1 (B) General Procedure for Asymmetric Hydrogenation of N-H imines Hydrochloride .. ..S6 (C) Analytical Data for the Hydrogenation Products . S6 (D) Imine Deuteration experiment...S11 (E) NMR Spectra of new products .. ...S12 (F) GC Charts for Hydrogenation Products ......S25 General: Unless otherwise noted all reactions were run under a nitrogen atmosphere, solvents and reagents were transferred by syringe. All manipulations involving [Ir(COD)Cl] 2 and (S,S)-f-binaphane were performed in a N 2 -filled glove-box. NMR spectra were recorded with a Varian spectrometer at 400 MHz ( 1 H NMR) and 100 MHz ( 13 C NMR) or 500 MHz ( 1 H NMR) and 125 MHz ( 13 C NMR) in CD 3 OD, DMSO-d 6 or CDCl 3 . Chemical shifts were reported in ppm downfield from internal Me 4 Si. Optical rotations were determined using a Perkin Elmer 341 MC polarimeter. HRMS were recorded on a Thermo LTQ Orbitrap hybrid mass spectrometer.

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.
