摘要
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 for a-amino acids.
