[2,3]-Wittig rearrangement initiated by 1,5-hydrogen atom transfer from an o-iodophenyl group on the α-carbon of allylic ethers by reduction with SmI2

Article abstract of DOI:10.1246/cl.1999.683

Intramolecular 1,5-hydrogen atom transfer of an aryl radical generated by reduction of an o-iodophenyl group on the allylic position of allyl ethers by SmI₂ regioselectively generates α-allyloxy carbanions, which undergo [2,3]-Wittig rearrangem
