An enantioselective difunctionalization of activated alkynes using chiral sulfinamide reagents is developed. It is an atom and chirality transfer process that allows for the modular synthesis of optically active α-amino acid derivatives under mild conditions. The reaction proceeds through an acid-catalyzed [2,3]-sigmatropic rearrangement mechanism with predictable stereochemistry and a broad scope
开发了使用手性亚磺酰胺试剂对活化炔烃进行对映选择性双官能化的方法。这是一种原子和手性转移过程,允许在温和条件下模块化合成光学活性 α-氨基酸衍生物。该反应通过酸催化的[2,3]-σ重排机制进行,具有可预测的立体化学和广泛的范围。
