Irradiation of inclusioncrystals of 2-(N-acyl-N-alkylamino)cyclohex-2-enones and N,N-dimethylphenylglyoxylamide with chiral host molecules gave the opticallyactive N-alkyl-1-azaspiro[3.5]-nonane-2,5-diones and 3-hydroxy-1-methyl-3-phenylazetidin-2-one, respectively. The crystal structure of the 1:1 inclusion complex of N,N-dimethylphenylglyoxylamide with (-)-trans-1,4-bis[3-(o-chlorophenyl)-3-hy

Abstract When an optically active host compound was mixed with an achiral guest compound in the solid state, host-guest inclusion crystals were formed by molecular movement and the achiral molecules became arranged in a chiral form in the inclusion crystals.

When optically active host compound was mixed with achiral guest compound in the solid state, host-guest inclusion crystals were formed by molecular movement and the achiral molecules became arranged in a chiral form in the inclusion crystals. Mixing of powdered (+)-host crystals with powdered (−)-guest crystals which are formed by a chiral arrangement of achiral guest molecules gave inclusion crystals of the (+)-host and the (+)-guest molecules newly produced through an inversion of the (−)-guest molecules during the complexation in the solid state.
