Abstract
Tetrasubstituted urea derived chloroamidinium salts reacted with α-amino esters to give new chiral pentasubstituted guanidines. Further alkylation with methyl iodide provided hexasubstituted guanidinium salts, which represent new chiral room temperature ionic liquids.
Key words
guanidines - guanidinium salts - ionic liquids - amino acids
