A novel protocol for the oxidative rearrangement of alkenes using in situ generated hypervalent iodine(III) was developed. This approach uses inexpensive, readily available, and stable chemicals (PhI, mCPBA, and TsOH) giving rearrangement products in yields comparable to those obtained using the more expensive commercially available [hydroxy(tosyloxy)iodo]benzene [HTIB or Koser’s reagent]. Additionally
建立了一种使用原位生成的高价碘(III)进行烯烃氧化重排的新方案。这种方法使用廉价,易于获得且稳定的化学品(PhI,m CPBA和TsOH),可提供重排产物,其收率可与使用较昂贵的市售[羟基(甲苯磺酰氧基)碘]苯[HTIB或Koser试剂]获得的产率相当。另外,对于1-甲基-2-四氢萘酮通过使用4-甲基-1,2-二氢萘的一步法环氧化/重排合成的替代协议米CPBA和TsOH被开发。
