Abstract
The study on the stereochemistry of some new 2-aryl-1,3-dioxanes beari ng identical geminal substituents in position 5 of the heterocycle was performed by means of NMR methods. The investigations pointed out the anancomeric structure of the compounds. The equatorial or axial prefe rences of the aryl groups were correlated with the Structure of the ot her substituents located in the acetal part of the heterocycle. The in fluence of the chirality on some 1,3-dioxanes obtained by the acetaliz ation of benzoin was investigated by means of the diastereotopicity of protons and carbon atoms.
