In the presence of water, several diamines and one triamine were mono-acylated at ambient to moderate temperatures using phenyl esters and a phenyl carbonate as acylation agents in good to excellent isolated yields. Both linear and cyclic polyamines were suitable substrates, and the acylating agents can be aryl and alkyl carboxylic acid esters.
在水的存在下,使用苯基酯和碳酸苯酯作为酰化剂,在室温至中等温度下将几种二胺和一种三胺单酰化,分离出的收率好至极好。线性和环状多胺都是合适的底物,酰化剂可以是芳基和烷基羧酸酯。
