Conformational analysis of oligo-1,3-dioxan-4-yls

Whereas simple 4,4′-bi(1,3-dioxanyl)s 16 and 19 displayed little conformational preference at the inter-ring bond, their derivatives 4 and 13, with equatorial methyl groups in the 5- and 5′-positions, each showed a strong conformational preference to populate a conformation with a gauche arrangement of the oxygen atoms. These results form the basis of a modular approach to oligo-1,3-dioxanyls 5, 6, and 29, in each of which a strong conformational preference prevails at all of the inter-ring bonds.
