Synthesis, Characterization, Antifungal and Antibacterial Activities of Novel Amide Derivatives of 1,3-Dioxolane
Bibliographic record
Abstract
L-Tartaric acid which is chiral compound and commercially available, was converted into 1,3-dioxolane. In the synthetic sequence, 1,3-dioxolane was first formed via protection and partial hydrolysis of L-tartaric acid. Treatment with altered substituted aromatic amines, 1,3-dioxolane gave the desired amides i.e. ethyl 2,2-dimethyl-5-(phenylcarbamoyl)-1,3-dioxolane-4-carboxylate 3a, 2-(4-(ethoxycarbonyl)-2,2-dimethyl-1,3-dioxolane-5-carboxamido)benzoic acid 3b, ethyl 5-(4-iodophenylcarbamoyl)-2,2-dimethyl-1,3-dioxolane-4-carboxylate 3c, ethyl 5-(2-chlorophenylcarbamoyl)-2,2-dimethyl-1,3-dioxolane-4-carboxylate 3d and ethyl 5-(2,4-dichlorophenylcarbamoyl)-2,2-dimethyl-1,3-dioxolane-4-carboxylate 3e. These chiral derivatives were purified through column chromatographic technique and characterized by different spectroscopic techniques i.e IR, 1H NMR, 13C NMR and EIMS. The antimicrobial activities of these compounds were determined at different concentrations against different strains of bacteria and fungi.

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.
