Conformational Preference in 1,3-Dithianes Containing 2-Phosphoryl, -(thiophosphoryl), and -(selenophosphoryl) groups. Chemical and Crystallographic Implications of the Nature of the Anomeric Effect

The operation of anomeric effect in all the title compounds studied was found.The magnitude of the anomeric effect was found to be larger than 10 kJ/mol.Crystallographic, spectroscopic, and thermodynamic data suggest that nS-?*C

CONFORMATION OF 2-PHOSPHORYL AND 2-THIOPHOSPHORYL 1,3-DITHIANES AND RELATED COMPOUNDS. COMMENTS ON THE ORIGIN OF S-C-P ANOMERIC INTERACTIONS.

A relationship was found between the γ-effect values in 13C NMR spectra and the solution conformation of the title compounds.Base-catalyzed equilibration of anancomeric 2-phosphoryl and 2-thiophosphoryl substituted 5-t-butyl-1,3-dithianes showed that axial preference increases in the order: Ph2P(S)Ph2P(O)(MeO)2P(O).Explanation of this phenomenon is proposed, based also on the results of molecular mechanics calculations.
