ROLE OF METHANOL IN CHIRAL COMBINATIONS OF HOST-GUEST MOLECULES IN THE INCLUSION CRYSTAL - STRUCTURE DETERMINATION BY X-RAY CRYSTALLOGRAPHY

hlorophenyl)-3-hydroxy-3-phenyl-1-propynyl]benzene (2) and s[3-(o-chlo rophenyl)-3-hydroxy-3-phenyl]anthracene (3) include one enantiomer of racemic guest compound when the complexation is carried out in toluene , but include the other enantiomer and MeOH in a 1:1:1 ratio when the complexation is carried out in MeOH; the X-ray crystal structure of a 1 : 1 : 1 complex of 3, (S)-(+)-2-methylpiperidine and MeOH is reporte d, and preparation of the new chiral host compound (3) is also describ ed.
