2,2,2-Trifluoroethyl Oxalates in the One-Pot Parallel Synthesis of Hindered Aliphatic Oxamides
European Journal of Organic Chemistry(2016)
摘要
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.
