Refluxing calix[4]-1,3-substituted benzaldehyde derivative(4) with glycine hydrazide derivative,we obtained a novel calix[4]arene hydrazone derivative(5) via“1+2”condensation in a yield of 78%.In the reaction of compound 4 with L-leucine hydrazide derivative at room temperature,lariat calix[4]-1,3-aza-crown(6) with chiral amino acid group as branched chain was synthesized via“1+1”addition in a yield of 70%.The preliminary extraction experiments suggested that hosting compounds 5 and 6 possessed good complexation abilities forα-amino acids.
