Studies on crystal structure of inclusion chiral crystal of ( S )-α-cyclopentyl-α-hydroxyl-α-thienylacetic acid with ( R )-α-methyl benylamine

The optically active α-cyclopentyl- α-hydroxyl-α-thienylacetic acid is obtained by the optical resolution of racemates with the chiral host α-methylbenylamine. The structure of the inclusion salt complex of two compounds was first elucidated by X-ray analysis.
