PBr₃-mediated reductive deoxygenation of α-aryl-pyridinemethanols to provide arylmethylpyridines is described, the alcohol substrate scope is explored, free radical trap TEMPO (2,2,6,6-tetramethyl-1-piperidinyloxy) is introduced, and the hydrogen source of the methylene product is defined. The unexpected reaction enabled us to prepare previously inaccessible, novel EP₁ antagonists.

PBr3介导的α-芳基吡啶甲醇的意外还原性脱氧：芳基甲基吡啶的合成

描述了PBr ₃介导的α-芳基吡啶甲醇的还原性脱氧以提供芳基甲基吡啶，探索了醇底物的范围，引入了自由基捕集剂TEMPO（2,2,6,6-四甲基-1-哌啶基氧基），以及氢定义了亚甲基产物的来源。出乎意料的反应使我们能够制备出以前无法获得的新型EP ₁拮抗剂。
