[reaction: see text] A practical highly diastereoselective synthesis of 1,2-diamines through carbon-carbon bond formation involving an ammonium ylide intermediate is reported for the first time. By treating methyl phenyldiazoacetate with arylamine and imine in the presence of dirhodium acetate, the erythro diastereomer of methyl 1,2-diaryl-1,2-diaminopropanoate is formed with stereochemical preferences
[反应:见正文]首次报道了通过涉及叶立德铵中间体的碳-碳键形成的一种实用的非对映选择性合成1,2-二胺的方法。通过在乙酸乙二胺的存在下用芳基胺和亚胺处理苯基重氮乙酸甲酯,可以形成立体化学偏好大于10:1的1,2-二芳基-1,2-二氨基丙酸甲酯的赤型非对映异构体。
