## Abstract The synthesis of 2,3‐didehydro[15]crown‐5 and −[18]crown‐6 derivatives 4a, b with vicinal α‐naphthyl groups at the double bonds starting from α‐naphthoin (3) is described. The barriers to rotation of the naphthyl groups were probed by MM2 and by dynamic ^1^H‐NMR spectroscopy. An achiral

## Abstract Complexes of 18‐crown‐6 with alkali–metal cations (Na^+^, K^+^, and Rb^+^), urea, and the uncomplexed crown ether were studied __in vacuo__ with the molecular dynamics method. Conformational data from these calculations (simulation times in the range from 6–15 ns) was compared with info
