Cyclopropenylcarbinyl cyanates, generated in situ by dehydration of the corresponding carbamates, underwent an efficient and 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 trichloroacetimidates.
Cyclopropenylcarbinyl cyanates, generated in situ by dehydration of the corresponding carbamates, undergo an efficient and stereoselective [3,3]‐sigmatropic rearrangement leading to the corresponding alkylidene(isocyanatocyclopropanes) that can be readily converted into various alkylidene(aminocyclopropane) derivatives in a one‐pot manner.
