摘要

Summary Mono-and trispiro-1, 3-dioxanes with mobile, fixed and “semimobile” structures were obtained by the condensation reaction of pentaerythritol with aldehydes and symmetrical or unsymmetrical ketones. The conformational analysis of the obtained compounds was undertaken by means of 1 H-NMR spectroscopy. The spiro-1, 3-dioxanes obtained with aldehydes or nonsymmetrical ketones represent fixed (“anancomeric”) ...
