Chiral 3-methyl-1,3-dihydroisobenzofurans (phthalans) having a carbonyl or a-hydroxybenzyl group in position I were synthesized by cyclization of the corresponding trimethyl[(S)-l-phenylethyl]ammonium. iodides. The configuration of the chiral centers in the products was determined by X-ray analysis.

diastereospecific reduction of (2S)-2-2-(1S)-1-(dimethylamino)ethyl]phenyl}-2-hydroxy-1,2-diphenylethanone is established by the XRD method. The analysis of shortened nonvalent intramolecular contacts testifies that the molecule is quite rigid, despite the presence of a large number of single valence bonds. Layered nature of molecular packaging is revealed.
