## 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
Prochiral 1,3-dihydroxyacetone forms racemic oxazolidine-with monocyclic by-products, but the spirobisimidazolidinone is accessible by reaction of 1,3-and oxazoline-type spiro[4.4]nonanes upon reactions with potassium (thio)cyanate and cyanamide. In contrast, 1,3-dichloroacetone with urea. The resol
