S. Wenger et al., SYNTHESIS OF 2 CALIX[4]ARENES CONSTRAINED TO A 1,3-ALTERNATE CONFORMATION BY DIAZA-BENZO CROWN-ETHER BRIDGING, Tetrahedron letters, 35(45), 1994, pp. 8369-8372
We report the synthesis of two calix[4]arenes constrained to a 1,3-alt
ernate conformation by diaza-benzo crown ether bridging. Preliminary b
inding properties of one of them is also described.
