摘要：
Amide based chiral tripodal receptor derivatives were synthesized under microwave irradiation in quite high yields (76%- 84%) and they were characterized by IR and 1D, 2D, H-1- and C-13-NMR spectroscopies. The recognition properties of these tripodal receptors towards some anions and organic ammonium salts were investigated by H-1-NMR titration in DMSO-d(6). The tripodal (S)-phenyl receptor demonstrated a highly significant enantiomeric selectivity towards the (S)-(-)-1-phenyletylammonium perchlorate (ERF= 91.74 S). [GRAPHICS] .
