Irradiation of inclusion crystals of 2-(N-acyl-N-alkylamino)cyclohex-2-enones and N,N-dimethylphenylglyoxylamide with chiral host molecules gave the optically active 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
用手性主体分子辐照2-(N-酰基-N-烷基氨基)环己-2-烯酮和N,N-二甲基苯基乙醛酰胺的包裹体晶体,得到旋光性的N-烷基-1-氮杂螺[3.5]-壬烷-2, 5-二酮和3-羟基-1-甲基-3-苯基氮杂环丁烷-2-一。N,N-二甲基苯基乙醛酰胺与(-)-反式-1,4-双[3-(邻氯苯基)-3-羟基-3-苯基丙-1-炔基]-的1:1包合物的晶体结构通过X射线衍射分析2,3,5,6-四氯-2,5-环己二烯-1,4-二醇。
