The present disclosure discloses non-invasive methods and kits for detecting, diagnosing, or monitoring pyrrolizidine alkaloid exposure in a subject, by measuring the amount or concentration of pyrrole-amino acid adduct in a biological sample (e.g., urine) from the subject and comparing the amount or concentration of pyrrole-amino acid adduct with a reference control subject.

(±)-4-Methyl-1-phenylthio-8-oxa-4-azabicyclo[5.2.1]decane-9,10-dione was efficiently converted into (±)-otonecine, which was regioselectively coupled with (E)-2-ethylidenehexanedioic acid to give a 12-membered otonecine diester.
