A simple parallel synthesis approach to unsymmetrical N1,N2-substituted aliphatic oxamides using methyl (2,2,2-trifluoroethyl) oxalate and bis(2,2,2-trifluoroethyl) oxalate was developed. The method was validated on a 52-membered set of the oxamides, derived mainly from hindered primary and secondary aliphatic amines, and gave the products with a high overall success rate in moderate yields.
开发了一种使用草酸甲酯 (2,2,2-三氟乙基) 和草酸双 (2,2,2-三氟乙基) 酯合成不对称 N1,N2 取代脂肪族草酰胺的简单平行合成方法。该方法在 52 元草酰胺组上进行了验证,草酰胺主要来自受阻的伯胺和仲脂肪胺,并以中等产率获得了具有高总体成功率的产品。
