Abstract
Fast methods for the removal of permanent amide exo-cyclic protective groups widely used in phosphoramidite-method DNA synthesis are desirable for many genomics and proteomics applications. In this communication, we present a method for the deprotection of a range of N-acyl deoxyribonucleosides (T, dA Bz, dC Bz, dC Ac, dG ibu, dG PAC) and synthetic oligodeoxyribonucleotides, ranging in length from 5-mer to 50-mer. Oligodeoxyribonucleotides were synthesized using standard amide protecting groups (dA Bz, dC Bz, dG ibu) and phosphoramidite chemistry on cis-diol solid phase support. This deprotection method utilizes 29% aqueous ammonia solution at 170 degrees C for 5 minutes under monomode microwave irradiation at a 20-nmole reaction scale. Reaction products were analyzed by TLC, RP-HPLC, CE, ESI-MS, real-time PCR, agarose gel electrophoresis, and by DNA uracil glycosylase (UDG) and phosphodiesterase I (PDE) enzymatic digestions.

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 it
