The presence of an amino substituent at the 2-vinyl position in substituted allyl vinyl ethers facilitates low-temperature rearrangements through [3,3]- or [1,3]-sigmatropic shifts, which lead to the aminoaldehydes (3) and (5), respectively.
在取代的烯丙基乙烯基醚中的2-乙烯基位置存在氨基取代基,可通过[3,3]-或[1,3]-σ位移促进低温重排,从而导致氨基醛(3)和(5), 分别。
