Acyclic bis-allylic ethers undergo a stereoconvergent 'one-pot' tandem [2,3]-Wittig-anionic oxy-Cope (AOC) rearrangement to give the same δ,ε-unsaturated aldehyde, with Esyn stereochemistry, as that obtained by AOC rearrangement of isolated [2,3]-Wittig products.
无环双烯丙基醚经历立体收敛的“一锅”串联[2,3] -Wittig-阴离子氧基-Cope(AOC)重排,得到与Esyn立体化学相同的δ,ε-不饱和醛,与通过AOC获得的分离的[2,3] -Wittig产品的重排。
