The diastereomeric racemates (3R, 5S; 3S, 5R) and (3R, 5R; 3S, 5S) 2- amino-3-hydroxy-3-phenyl-5-(4'-chlorophenyl) cyclopentene-1- carbonitriles were synthesized by reaction of low-valent titanium reagent (TiCl~4-Zn) with α, α-(4-chlorophenyl) (dicyanomethyl) methyl phenyl ketone. Their configurations were determined by X-ray analysis.

Key words: TITANIUM CHLORIDE, CYCLOPENTENE P, DIPHENYLHYDROXYETHANONE P, SYNTHESIS, CHLOROBENZENE P, CONFIGURATION, TIRON, AMINONITRILE, CRYSTAL STRUCTURE, DIMETHYL-OCTAHYDRO-NAPHTHANITRILE
