FROM THE STEREOCHEMISTRY OF A MOLECULE TO THE STEREOCHEMISTRY OF A CRYSTAL: CHIRAL CRYSTALLIZATION OF ENDO-ISOMERS COMPARED WITH CENTROSYMMETRIC CRYSTALLIZATION OF EXO-ISOMERS OF THIIRANE AND OXIRANE DERIVATIVES OF PHENYL- SUBSTITUTED SEVEN-MEMBERED ACETAL

Abstract: The chiral type of crystallization of endo-isomers of 4-phenyl-3,5,8-trioxabicyclo[5.1.0]octane and 4-phenyl-3,5-dioxa-8-thiabicyclo[5.1.0]octane and the formation of racemic crystals by molecules corresponding exo-isomers are established. The relationship between the structural organization of molecules and the stereochemical type of intermolecular interactions and the formation of different types of crystals is analyzed.
