Synthesis of a new lariat diaza crown ether compounds

New of lariat ether compounds were synthesized as cationic and molecular acceptors. Lariat ethers 7a to 7b were prepared by reaction of macrosyclicdiamide 5 and phenoles in the presence of paraformaldehyde by refluxed in dry toluene. The structures were characterized by FT-IR, 1HNMR, 13CNMR and Mass spectrometry analyses.
