Abstract
Abstract The stereochemistry of some new 1,3-dioxanes with brominated chiral groups located in the (a)ketalic part of the heterocycle, obtained by a regioselective radicalic bromination reaction, was investigated by NMR methods. The experiments demonstrated the fixed or flipping structures of the compounds. The influence of the chiral carbon atoms was analyzed by means of the diastereotopicity of protons and carbon atoms. In the case of polychiral compounds, the diastereoselectivity of the bromi-nation reaction was studied.
