An iridium-catalyzed diastereoselective amination of alcohols with chiral tert-butanesulfinamide was developed under basic conditions, affording the optically active secondary sulfinamides in high yields and diastereoselectivities. The removal of the sulfinyl group from sulfonamides allowed a facile access to a wide range of α-chiral primary amines. This synthetic strategy was further applied in the
在碱性条件下,用手性叔丁烷亚磺酰胺进行了铱催化的醇的非对映选择性胺化反应,从而以高收率和非对映选择性提供了光学活性仲亚磺酰胺。从磺酰胺中除去亚磺酰基使得可以容易地获得各种α-手性伯胺。将该合成策略进一步应用于市售药物(S)-卡巴拉汀和NPS R-568的合成。
