A few facile synthetic pathways for bicyclic aminopyridinol antioxidants are presented. Attachment of a long alkyl chain to the bicyclic pyridinol scaffold was established using ester linkage. Non-substituted pyrrolopyridinols and 1,3-oxazine-fused pyridinols were also synthesized as novel antioxidant scaffolds. Antioxidant activities were measured by a radical clock method and new compounds prepared are comparable to the best bicyclic aminopyridinol antioxidants.
本文介绍了一些双环氨基吡啶醇抗氧化剂的简便合成途径。利用酯连接将长烷基链连接到双环吡啶醇支架上。还合成了非取代的吡咯并吡啶醇和 1,3-噁嗪融合的并吡啶醇作为新型抗氧化剂支架。通过自由基时钟法测定了新化合物的抗氧化活性,结果表明它们与最好的双环氨基吡啶醇抗氧化剂相当。
