Oxidation of α-amino nitrile 4 with ozone gave rise to a mixture of α-imino nitrile 5 and a novel fragmentation product of 6 in one-step. The mixture was converted to a variety of α-substituted α-amino acids 7 in high yields, which enabled the asymmetric transferring Strecker synthesis to be a widely useful method.
用臭氧氧化α-氨基腈4可以一步合成α-亚氨基腈5和6的新型碎片产物的混合物。将该混合物高产率地转化为多种α-取代的α-氨基酸7,这使得不对称转移Strecker合成成为一种广泛有用的方法。
