Addition of N-acetylcysteine to linoleic acid hydroperoxide.

Catalyzed by 10(-5)M ionic iron in 80% ethanol, N-acetylcysteine added to linoleic acid hydroperoxide, forming a thiobond. Reaction of a specific isomer of hydroperoxide, 13-hydroperoxy-trans-11, cis-9-octadecadienoic acid, and N-acetylcysteine, forms a number of products, of which two were identified as addition compounds. One addition product was 9-S-(N-acetylcysteine)-13-hydroxy-10-ethoxy-trans-11-octadecenoic acid, and the other was 9-S-(N-acetylcysteine)-10, 13-dihydroxy-trans-11-octadecenoic acid.
