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.展开更多
