A practical and straightforward approach for the highly stereoselective synthesis of β-amino sulfones was developed. With lithium bis(trimethylsilyl)amide as the base, the corresponding sulfone-stabilized carbanion derived from alkylphenyl sulfone can be transferred to N-(tert-butylsulfinyl) aldimines in excellent yields and with high diastereoselectivity.
开发了一种实用且直接的方法,用于β-氨基砜的高度立体选择性合成。和双(三甲基甲硅烷基)氨基锂作为碱,衍生自烷基苯基砜的相应的砜稳定的碳负离子可以优良的收率和高的非对映选择性转移到N-(叔丁基亚磺酰基)亚胺上。
