The chiral compound 5H-imidazol[2,3-b]isoquinoline-l-ethanol-5-one-1,2, 3, 10b-tetrahydro- β（S）-phenyl-3（S）-phenyl was synthesized from the direct condensation of 2- cyanophenyacetonitrile with optically active ...The chiral compound 5H-imidazol[2,3-b]isoquinoline-l-ethanol-5-one-1,2, 3, 10b-tetrahydro- β（S）-phenyl-3（S）-phenyl was synthesized from the direct condensation of 2- cyanophenyacetonitrile with optically active （S）-（＋）-2-phenylglycinol in chlorobenzene under dry, anaerobic conditions. ZnCl2 was used as a Lewis acid catalyst in this reaction, and the structure of this compound was determined by X-ray diffraction, NMR, MS and IR.
