xylamines are readily accessible as imine surrogates, which are bench stable and could quantitatively generate the corresponding imines for in situ applications. An unpresented catalytic asymmetric method for the synthesis of α-amino esters and ketones from novel imine surrogates, N,O-bis(tert-butoxycarbonyl)hydroxylamines, as well as its preliminary mechanistic studies are reported. A variety of optically
N,O-双(叔丁氧基羰基)羟胺很容易以亚胺代用品形式获得,具有台架稳定性,可以定量生成相应的亚胺用于原位应用。报道了一种从新型亚胺代孕酸酯,N,O-双(叔丁氧基羰基)羟胺合成α-氨基酯和酮的无催化催化不对称方法,以及其初步的机理研究。以优异的产率和对映选择性(高达99%的产率和> 99%的ee)获得了多种光学富集的产物。
