I. Grosu et al., Synthesis and stereochemistry of some new 1,3-dioxane derivatives obtainedfrom 5-aryl-2-furaldehydes, REV RO CHIM, 45(9), 2000, pp. 877-882
The NMR investigations on the stereochemistry of some new 1,3-dioxane deriv
atives obtained from 5-aryl-2-furaldehydes revealed the anancomeric structu
re of the saturated heterocycle in all studied compounds. The free rotation
of the furan ring and of its aromatic substituent has been observed even a
t low temperature and even if the aromatic substituent was a phenyl ring be
aring in ortho position a bulky group (e.g. Iodine).
