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 synthesis of the marketed pharmaceuticals (S)-rivastigmine and NPS R-568.
发展了铱催化的醇与手性叔丁基亚磺酰胺的非对映选择性胺化反应,在碱性条件下以高产率和高非对映选择性得到了光学活性的仲磺酰胺。磺酰胺基的脱除为广泛的α-手性伯胺提供了一种简便的方法。该合成策略进一步应用于市售药物(S)-利伐斯的明和 NPS R-568 的合成。
