asymmetric synthesis and chemical modification of p-bromophenyl methyl sulfoximine (2) is described. Starting from p-bromophenyl menthyl sulfinate (5), enantiopure 2 can be obtained in a short reaction sequence involving a well-established substitution reaction followed by stereospecific imination with O-mesitylenesulfonylhydroxylamine (MSH). Palladium-catalyzed Buchwald/Hartwig, Suzuki, and Stille
描述了对-溴苯基甲基亚磺酰亚胺(2)的不对称合成和化学修饰。从对-溴苯基薄荷基亚磺酸盐(5)开始,可以在短的反应序列中获得对映体纯2,所述短的反应序列包括建立良好的取代反应,然后用O-间苯二甲磺酰基羟胺(MSH)进行立体定向亚胺化。钯催化的Buchwald / Hartwig,Suzuki和Stille偶联反应使亚砜亚胺芳基的变化范围很大,否则很难实现。p的并入-吗啉代取代的衍生物成为假三肽证明了该新型亚磺酰亚胺衍生物的适用性。
