Highly enantioselective palladium-catalyzed formal hydrogenolysis of racemic N-sulfonyloxaziridines has been realized, providing a novel access to sultams with up to 99% ee. Preliminary mechanistic insights revealed that the reaction proceeded through a N–O bond cleavage, dehydration, and the sequential asymmetric hydrogenation.
已经实现了高度对映体选择性的钯催化的外消旋N-磺酰基恶唑烷的正式氢解反应,从而提供了一种新的途径来获得ee高达99%的杜鹃花。初步的机理研究表明,反应是通过N-O键裂解,脱水和顺序不对称氢化进行的。
