The novel lariat calix[4]-1,3-aza-crowns with chiral amino acids groups as branched chain (5a) and (5b) were synthesized via "1+1" addition of calix[4]-1,3-substituted benzaldehyde derivative (4) and amino acids hydrazide derivatives (3a) and (3b) in yields of 70% and 75%, respectively.

The first examples of lariat calix[4]-1,3-aza-crowns with chiral amino acid groups as branched chains (5a and 5b) were designed and synthesized via a 1+1 addition reaction of calix[4]-1,3-substituted benzaldehyde derivative (4) and amino acid hydrazide derivatives (3a and 3b) in yields of 70% and 75%, respectively. The preliminary extraction experiments suggested that hosts 5a and 5b possessed good complexation abilities for-amino acids.
