Although the lithium enolate undergoes [2,3]-sigmatropic rearrangement to give , the silyl ketene acetals undergo [3,3]-sigmatropic rearrangement to give . This is the first reported [3,3]-sigmatropic rearrangement of a 1,1-dioxy-3-oxa-1,5-diene.
尽管烯醇锂进行[2,3]-σ重排,但甲硅烷基烯酮缩醛进行[3,3]-σ重排。这是第一个报道的1,1-二氧基-3-oxa-1,5-二烯的[3,3]-σ重排。
