stereoselective [3,3]‐sigmatropic rearrangement leading to the corresponding alkylidene(isocyanatocyclopropanes), which could be converted into various alkylidene(aminocyclopropane) derivatives in a one‐pot manner. This transformation complements the repertoire of sigmatropic rearrangements involving cyclopropenylcarbinol derivatives and in particular, the previously reported Overman rearrangement of cyclopropenylcarbinyl
通过相应的氨基甲酸酯脱水原位生成的环丙烯基羰基氰酸酯,经过高效且立体选择性的[3,3]-σ重排,导致相应的亚烷基(异氰酸根合环丙烷),可以将其转化为多种亚烷基(氨基环丙烷)衍生物。锅方式。这种转变补充了涉及环丙烯基甲醇衍生物的σ重排的所有组成,特别是先前报道的环丙烯基羰基三氯乙酰亚胺酸酯的超人重排。
