THE SYNTHESIS OF 4H-PYRAN CONTAINING HEMISPHERANDS VIA PYRYLIUM SALTS

Two new hemispherands 2a and 2b containing a central 4H-pyran unit were synthesized via appropiately substituted 2,6-phenyl pyrylium salts; largest ΔG0 values of complexation of 2a and 2b with different alkali picrates are found for Na(+) and K(+).

4H-Pyran and Pyrylium Hemispherands: Partly Preorganized Ionophores with Reactive Molecular Cavities

The synthesis and reactivity of a 2,6-diaryl-substituted pyrylium cation incorporated in an 18-membered macrocycle (3a,b) has been studied.Hemispherands with a central pyridine (4a,b) and with alkyl- or phenyl-substituted pyridinium ions (5a,b) were obtai
