The main objective of this work was to study the rearrangement reactions of 1-alkyl-2-[(phenylsulfonyl)methyl]pyridinium iodides in the presence of various nucleophiles, leading to N-alkyl-2-(phenylsulfonyl)aniline derivatives. The best results were achieved with alkylammonium sulfites, leading to pyridine ring opening followed by recyclization to give diphenyl sulfone derivatives in up to 78% yields
这项工作的主要目的是研究在各种亲核试剂的存在下1-烷基-2-[(苯磺酰基)甲基]吡啶鎓碘化物的重排反应,从而产生N-烷基-2-(苯磺酰基)苯胺衍生物。用亚烷基磺酸铵可获得最佳结果,导致吡啶开环,然后环化以最高78%的收率得到二苯砜衍生物。
