In our published paper, we have reported the formation of hydrazine derivatives by electrophilic amination using N-Boc-Otosylhydroxylamine. From the available literature (J. Vidal et al. Chem. Eur. J. 1997, 3, 1691; J. G. Krause et al. Tetrahedron Lett. 2010, 51, 3568; W. Hartmann Synthesis 1988, 807; A. Armstrong et al. Org Lett. 2005, 7, 713), we conclude that the structures assigned are erroneous
在我们发表的论文中,我们报道了使用 N-Boc-Otosyl 羟胺通过亲电胺化形成肼衍生物。来自现有文献(J. Vidal 等人 Chem. Eur. J. 1997, 3, 1691; JG Krause 等人 Tetrahedron Lett. 2010, 51, 3568; W. Hartmann Synthesis 1988, 807; A. Armstrong 等人. Org Lett. 2005, 7, 713),我们得出结论,指定的结构是错误的,实际产物是异构脲衍生物,由 Lossen 重排形成,如下所示。
