Abstract

The Stevens and Sommelet–Hauser rearrangements of ammonium ylides are known as useful transformations for organic synthesis because they convert a readily accessible CÀN bond into a new CÀC bond.[1] The Stevens rearrangement has been widely used for the asymmetric synthesis of αamino acid derivatives,[2, 3] whereas the Sommelet–Hauser rearrangement is much less common because it usually competes with the [1, 2] Stevens ...
