S. Watanabe et al., SYNTHESIS OF NOVEL LANTERN-SHAPED MOLECULES BASED ON RESORCIN[4]ARENEAND M-TERPHENYL UNITS, Tetrahedron letters, 36(42), 1995, pp. 7677-7680
Novel lantern-shaped molecules with a large enclosure were synthesized
by taking advantage of resorcin[4]arene and m-terphenyl units as the
capping and bottom fragments, respectively. Two conformers with differ
ent cavity volume were obtained selectively by changing the substituen
t on the bottom unit.
